+# The Path to Raku
+
+This document describes the steps to be taken to effectuate a rename of
+`Perl 6` to `Raku`, as described in issue #81.  It does not pretend to be
+complete in scope or in time.  To change a name of a project that has been
+running for 19+ years will take time, a lot of effort and a lot of
+cooperation.  It will affect people in foreseen and unforeseen ways.
+
+## Language changes
+
+### .perl
+
+The `.perl` method should be deprecated in 6.f, and removed in 6.g.  It
+should be replaced by a `.raku` method, which will be specified in 6.e
+(Rakudo can provide for it as soon as implemented). This could be
+implemented by a global search/replace of `.perl` to `.raku` (both in
+method names and in calls) in `src/core`, `src/Perl6` and `lib`.  A new
+`Mu.perl` method should be added that will later come to issue a
+DEPRECATED message, and then delegate to `.raku`.
+
+To retain compatibility with modules that declare a method `perl`, the
+default `raku` method should check if the type in question has a
+non-default `perl` method (that is, not the one from `Mu`) and, if so,
+call it. Once `.perl` is deprecated, it should issue the deprecation
+warning also.
+
+Renaming to `.code` currently clashes with `CallFrame.code`, visually clashes
+with the `.codes` method, and it being a generic name, probably also clashes
+with CPAN and DarkPan Perl 6 modules.
+
+### Perl and $*PERL
+
+`$*RAKU` and the `Raku` class will be the replacement of `$*PERL` and the
+`Perl` class, which initially will just be aliases.  At a language boundary
+switch, they will become actual type declarations.
+
+### `PERL6LIB`
+
+A `RAKULIB` environment variable will be introduced into a Rakudo release,
+and specified as part of 6.e. If found in the environment, it will be used in
+favor of `PERL6LIB`. From 6.f, use of `PERL6LIB` will issue a deprecation
+warning.
+
+### `PERL6_HOME`
+
+This was only very recently introduced, and is likely not in wide use yet.
+We could consider immediately replacing it with `RAKU_HOME` in an upcoming
+Rakudo release, perhaps with a short-term fallback/warning - or error - if
+it's missing, but `PERL6_HOME` is found.
+
+### Pragmas
+
+The `use isms <Perl5>` should **NOT** be changed to `use isms <Perl>`.
+Similarly `use Foo:from<Perl5>` and the `:lang` parameter to `EVAL` should
+not be changed as to allow more flexibility should the Perl 5 community
+decide on a name change as well.
+
+### Versioning
+
+Because the next language release (6.e) may not coincide with
+the rename, no changes to versioning of the language need to be done.  The
+next release *will* however be a Raku release, but should be otherwise
+completely compatible with previous releases.
+
+A new *language* version would be the opportunity to make the name change
+more widely known with associated marketing efforts.  But this will *not*
+be with the next (monthlyish) release.
+
+Given we are no longer forced to have "6" in the version, there are now
+more options to do language versioning properly, and this aspect will
+need to be discussed separately at a later time.
+
+### NQP
+
+The acronym for NQP is Not Quite Perl.  It stays that way, so no changes
+to documentation are needed.  Generally, the MoarVM / NQP construct should
+not matter a lot for the average user.
+
+## Documentation changes
+
+Wherever `Perl 6` is mentioned in the documentation, this should be changed
+to `Raku`.  A mention of `Perl 6` in the glossary should remain, and maybe
+in the documentation of the `.perl` (to be renamed to `.raku`) method.
+
+A mention to `Perl 6` should only occur when a redirect from `docs.perl6.org`
+has been detected / or a special URL to redirect to has been followed (e.g.
+https://documentation.raku-lang.org/?from=perl6).
+
+## Website changes
+
+Websites that have `perl6` in their name, should redirect to their
+equivalent with a 301 (Moved Permanently).  Some way should be devised that
+if someone is redirected, that a small explanation of the name change is
+offered and that the visitor is indeed at the place they were planning to
+be.
+
+## IRC Channels
+
+The IRC channels used by Perl 6 users on freenode (#perl6\*) will need to
+be renamed or closed / opened with the new name (#raku\*).  New joins should
+be forwarded to the new channels.
+
+Colabti.org will need to be asked to log these channels, so that we can have
+backlog again.  Unfortunately, it appears to be too difficult to migrate #perl6
+logs, so the same approach that was done when the #perl6-dev channel was
+created, will need to be followed.  So searching the logs will need to be
+done on the old names.
+
+Further down the road, it would probably be a wise idea to make IRC channel
+logging one of the infrastructure tasks.
+
+## External references
+
+Many places on the Internet refer to `Perl 6`.  These references will need
+to be changed to `Raku`, with a small explanation of the name change.  This
+should be a coordinated effort to avoid duplicity of work, and to make sure
+that the explanation of the name change is consistent.
+
+Many sites, such as Reddit and StackOverflow, use implicit / explicit `perl6`
+tags.  These will need to be changed or have a `raku` tag added, possibly
+with cooperation of the administrators.  It should be prevented that "Perl 6"
+all of a sudden becomes hard to find on these sites.
+
+Sites such as PerlMonks appear to be really `Perl` (aka `Perl 5`) focused,
+and could possible make that clear in their description, or change their
+description to specifically include `Raku`.  It would look like the
+`/r/perl` Reddit description can be changed to indicate that only `Perl 5`
+questions are on topic there.
+
+## Technical changes
+
+All technical changes should make sure that all existing scripts continue
+to work without change in the foreseeable future. Additional DEPRECATED
+messages will be introduced at point of a 6.e language change.
+
+### Executables
+
+As some packagers have already done, the executable should be called `rakudo`,
+since `rakudo` is the name of the implementation.  `raku` and `perl6` should
+be symlinks.  If at all technically possible, running a script using the
+`perl6` as the executor should provide a DEPRECATED warning at some point.
+
+### Extensions
+
+The extension `.rk` for scripts, `.rkm` for modules, and `.rd` for
+documentation (POD6) will become the defacto standards for files containing
+`Raku` code or documentation.  The old `.pm`, `.pm6` and `.pod6` extensions
+will continue to be supported for 6.e.  In 6.f, the `.pm`, `.pm6` and `.pod6`
+extensions should be marked as DEPRECATED, causing a message to be generated
+when the module is loaded.
+
+On Windows, installers should add a `.rk` association alongside the `.p6`
+association for the time being. Around the time of 6.f, a `.p6` association
+could be deselected by default, and perhaps dropped entirely by 6.g.
+
+### Testing
+
+Roast continues to be the specification of the language.  Only the name
+of the language it specifies, changes.  Internal references to `Perl 6`
+will need to be changed.
+
+## Mascot
+
+Camelia will remain the mascot.  The only thing that should change there
+is that it is the mascot of `Raku` rather than `Perl 6`.  The fact that the
+wings contain a "P" and a "6" is obscure enough to not be an issue, and could
+be seen as a lasting tribute (easter egg) to the origin of "Raku".
+
+## Marketing changes
+
+Renaming `Perl 6` to `Raku` is an event that should be used to get maximum
+marketing result.  This will need `Raku` marketing materials.  Announcement
+should be coordinated, e.g. by a blog post on `opensource.com` or similar
+outlets, followed up by links on the various social media outlets, such as
+Twitter, Facebook, Hacker News, Reddit, etc.
+
+Specific attention should be given for the announcement of Raku in non-latin
+script countries (such as India, Japan, China, Taiwan) by making sure any
+announcements are also translated into appropriate languages for these regions.
+Raku, with its more than excellent Unicode support, should be able to make a
+big splash for developers in those regions.
+
+## Social Media
+
+Users who want to blog about `Raku` are suggested to always at least mention
+`Raku Programming Language` in their blog post, or in the boilerplate of their
+blog posts.  Mentioning of `Perl 6` in such blog posts is **discouraged**,
+unless the blog post is actually about the renaming process or historical
+matters.
+
+When using social media that use hash-tags, users are suggested to use the
+`#raku-lang` hash-tag, and **not** use the `#perl6` hash-tag, unless the
+post is actually about the renaming process or historical matters.
+
+Of course, the same applies to more official social media usage by the core
+development team.
+
+## Ecosystem changes
+
+From the standpoint of users, there should not be any change: `zef` should
+continue to do what it does.  The information about what is in the ecosystem,
+is not related to the "perl 6" name at the moment, so does not need any
+change either.
+
+On PAUSE, Perl 6 distributions are automatically uploaded to a "Perl6"
+subdirectory, but this is completely transparent to both the author as well
+as anything else that needs to look at that as long as a file `META6.json`
+exists in the distribution.  So for the foreseeable future, no changes will
+be needed there.
+
+Should PAUSE decide to no longer support `Raku` modules in its system, then
+alternatives will need to be found and/or implemented.
+
+## Effects on modules in ecosystem
+
+A guide for existing module developers will be provided, which will offer
+suggestions of what to do about the rename. If we can generate PRs that's
+perhaps also helpful, though we might want that to be opt-in: authors with
+a load of modules might be unpleasantly surprised to wake up one morning
+to an inbox full of PRs.
+
+Such a guide should help authors with modules that either mention "perl6"
+or "p6" in their repo name, or mention "Perl 6" in their documentation.
+
+A proposed draft of such a guide is included at the end of this document.
+
+## Effects on running sub-projects
+
+Projects, such as Comma and Cro do not need any notifications, but other
+sub-projects may need to get advance notice.  An inventory of these
+sub-projects will need to be made, and their maintainers be notified
+individually, rather than through social media.  This is both to stress
+the urgency for a change, and to be able to present a "clean slate" to the
+general public when announcements about the name change *are* made through
+social media.
+
+## Effects on books
+
+Currently printed copies of books will probably need a sticker like "Covers
+the new exciting Raku programming language).
+
+Perl 6 books that have been open sourced, can be adapted by the community or
+the original author: a "Migration Guide for Book Authors" should help authors
+with this.  Since ebook sales currently outperform printed books by an order
+of magnitude, preparing another version of an ebook should be a relatively
+small effort, which can actually be distributed among many individuals using
+modern source control techniques.
+
+## Effects on the Perl community
+
+There is a (small) part of the Perl community that welcome the rename, as they
+don't want anything to do with the language and are glad to disassociate it
+from the Perl name.  There are community members with an active interest in
+both Perl 5 and Raku, and some of those who only do one or the other still
+feel there is much to be learned from, and shared with, each other, especially
+given the many shared design values of the languages.
+
+The name change of `Perl 6` to `Raku` is also intended to have a healing
+effect on a community that has been effectively split for many years.
+It is the hope of the Raku core development team that future events will
+continue to cater for both `Perl` as well as `Raku` presentations.
+
+## Effects on user groups
+
+Each Perl user group (Perl Monger group) will have to decide for themselves
+what they want to do with this new situation.  More active groups in the
+past years, have started using the services of online meeting organizers
+such as MeetUp.  To indicate the changed situation, it may be a good idea
+to change the names of such groups, e.g. from "Foo Perl Mongers Meeting" to
+"Foo Perl Family Meetup" or "Foo Perl Community Meetup".  Should a user
+group decide to only focus on `Perl 5` or `Raku` only, then they are of
+course open to not change their name, or to change it to something like
+"Foo Raku Meetup".  This could coincide with the official announcement,
+and maybe special events to celebrate the name change.
+
+## Effects on events
+
+Event organizers are, as always, completely free in the naming of their events.
+If an event would like to cater for both `Perl` and `Raku` attendees, then
+this should be reflected in the name of the event.  An event with just `Raku`
+in its name, would appear to cater only for attendees interested in `Raku`.
+An event with just `Perl` in its name, would appear to cater for attendees
+interested in `Perl 5` only.  Suggestions for naming events are (where "Foo"
+is a place / country name):
+
+    The Foo Perl Community Workshop
+    The Foo Perl Family Workshop
+    The Foo Perl and Friends Workshop
+    The Foo Perl and Raku Conference
+    The Foo Raku and Friends Workshop
+
+etc. etc.
+
+## Relationship with The Perl Foundation
+
+No changes should be necessary with regards to the relationship with The
+Perl Foundation.  But this is mostly up to The Perl Foundation.  A suggestion
+would be to make the website of The Perl Foundation more general: a Perl
+Family.  With equal attention for Perl, Raku, RPerl and CPerl, and emphasis
+on continued development on all projects.
+
+Should The Perl Foundation decide to not want to have anything to do with
+`Raku`, only then should an alternate organisational support be discussed.
+
+However, since "Yet Another Society" is doing business as "The Perl
+Foundation", maybe it is an idea to create another "doing business as"
+called "The Raku Foundation".  Which would make it clear that "The Perl
+Foundation" is for Perl 5 only, whereas "The Raku Foundation" would be for
+Raku only.  While both are part of the Perl Mindset in the "Yet Another
+Society".
+
+## Draft guide for module developers
+
+The Raku team are grateful to all those who have developed modules for the
+language. We recognize that most contributors are doing so on a volunteer
+basis, and that this work is often done in one's (lack of) free time.
+
+This guide provides some suggestions on how module authors can handle the
+Perl 6 to Raku renaming. While there is a suggested timeline here, it is
+to be interpreted as "at your convenience", rather than an expectation to
+do these things quickly.
+
+### In the period immediately after the rename is agreed...
+
+You might consider:
+
+* Mentioning Raku in your module's README or other documentation. It's up to
+  you if you wish to have something like "Raku (formerly Perl 6)", to stay
+  findable for such searches for some time, or to simply adopt the Raku name
+  right away.
+* Renaming the GitHub repository if it contains `p6` or `perl6` (remember to
+  update the `sources` entry in `META6.json` if doing this).
+
+In this interest of your module continuing to work with existing Rakudo
+installations, please *do not*, at this point:
+
+* Change module file extensions away from `.pm6`
+* Rely on `.raku`, `Raku`, `$*RAKU`, and similar
+
+### Around the release of 6.e...
+
+This is expected to happen in 2020. At this point, you might consider:
+
+* Changing module file extensions (remembering to update `META6.json`)
+* Switching to use `.raku`, `Raku`, `$*RAKU`, and similar in the module's
+  code (most modules will not be doing this anyway)
+* Dropping remaining mentions of Perl 6 in the documentation, unless it is
+  there for historical interest

+# SWOT analysis of renaming Perl 6 to Raku
+
+## Strengths
+
+- removes the confusion that Perl 6 is Perl version 6 (a new version of Perl).
+- frees up higher versioning of "Perl"
+- no longer linked to bad reputation of "Perl"
+- removes source of Perl community stress
+- is a cool name that should appeal to younger people
+- name should better appeal to non-english native speakers
+- should be easier to get distinctive TIOBE rating
+
+## Weaknesses
+
+- will *still* be linked to "Perl" because of historical connection
+- Perl 6 books will not know of name change, and thus continue to "squat"
+- Perl 6 blog posts will not know of name change, and thus continue to "squat"
+- may be hard to find using search engines, at least initially
+- must start with TIOBE rating from scratch
+- in social media, #raku as a tag is overloaded with Japanese pottery meaning
+
+## Opportunities
+
+- could be considered a brand new language, and thus more interesting to some
+- should re-invigorate development
+- should re-invigorate marketing
+- with better branding, should be able to get easier sponsorships / grants
+- may get core developers who have left, back into the core team
+- could be marketed as a programming language without corporate backing, and thus free from corporate influencing / agenda
+- could be marketed on its own, with its own strengths, such as multi-paradigmity and concurrency, as well as coverage of the Unicode standard
+- could be marketed as the 100-year language properly
+- current Perl 6 books could be updated while changing the name
+- current Perl 6 blog posts could be better marked with TIOBE tag (as they presently are not tagged correctly in general)
+- reworked documentation could have *all* pages properly TIOBE tagged
+- in social media, use new, distinctive #rakulang tag
+
+## Threats
+
+- may lose current users
+- may lose current core developers
+- may lose current book writers
+- may lose support from local Perl user groups (PerlMongers)
+- may lose support of organizations such as The Perl Foundation, EPO, YEF
+- may be made fun of as the language that cannot make up its mind
+- may cause incompatibities / breakage that will reflect badly on overall image
+- could drain critical mass from Perl 5 events
+- could drain critical mass from Raku events
+- may not get enough traction to grow anyway
