- DDuncan's Str types
subtype 'Str'
=> as 'Value'
=> where { Encode::is_utf8( $_[0] ) or $_[0] !~ m/[^0x00-0x7F]/x }
=> optimize_as { defined($_[0]) && !ref($_[0]) };
subtype 'Blob'
=> as 'Value'
=> where { !Encode::is_utf8( $_[0] ) }
=> optimize_as { defined($_[0]) && !ref($_[0]) };
- type unions
Add support for doing it with Classes which do not have
a type constraint yet created
- type intersections
Mostly just for Roles
- inherited slot specs
'does' can be added to,.. but not changed
(need type unions for this)
- proxy attributes
a proxied attribute is an attribute
which looks like an attribute,
talks like an attribute, smells
like an attribute,.. but if you
look behind the curtain,.. its
over there.. in that other object
(... probably be a custom metaclass)
- local coerce
[13:16] mst stevan: slight problem with coerce
[13:16] mst I only get to declare it once
[13:17] mst so if I'm trying to declare it cast-style per-source-class rather than per-target-class
[13:17] mst I am extremely screwed
[13:17] stevan yes
[13:17] stevan they are not class specific
[13:18] stevan they are attached to the type constraint itself
[13:18] * stevan ponders anon-coercion-metaobjects
[13:18] mst yes, that's fine
[13:19] mst but when I declare a class
[13:19] mst I want to be able to say "this class coerces to X type via <this>"
[13:19] stevan yeah something like that
[13:19] stevan oh,.. hmm
[13:20] stevan sort of like inflate/deflate?
[13:20] stevan around the accessors?
[13:25] * bluefeet has quit (Remote host closed the connection)
[13:27] mst no
[13:27] mst nothing like that
[13:27] mst like a cast
[13:31] mst stevan: $obj->foo($bar); where 'foo' expects a 'Foo' object
[13:31] mst stevan: is effectively <Foo>$bar, right?
[13:32] mst stevan: I want to be able to say in package Bar
[13:32] mst stevan: coerce_to 'Foo' via { ... };
[13:32] mst etc.
[13:53] stevan hmm
- rationalize all the get_X methods for classes (and roles)
We have get_attribute, get_attributes_list, get_all_attributes,
etc. First, we need to make the method names consistent. If something
returns an attribute vs a name, that needs to be clear from the method
name. We also need to make sure that local vs. "entire inheritance
chain" is clear from the name.
Finally, kill all the public get_X_map methods. The hashref it returns
is the internal reference, and the fact that it _is_ a hashref is just
an implementation detail.
This is mostly a CMOP change.
- Metaclass constructors
There's a _lot_ of different conventions in here. Some things to consider:
* new vs _new
* allowing new( 'name', %args ) vs ( name => 'name', %args )
* Method->wrap vs Method->new
- Role & Class
These two share a _lot_ of logic, but it's not via shared code. Maybe
implement some sort of role-lit internal thing so we can have a
"HasAttributes" and "HasMethods" role for classes and roles.
- Moose::Meta::TypeConstraint::Parameter{izable,ized}
The relationship between these two classes is very odd. In particular,
this line in Parameterized is insane:
foreach my $type (Moose::Util::TypeConstraints::get_all_parameterizable_types()) {
Why does it need to loop through all parameterizable types? Shouldn't
it know which parameterizable type it "came from"?
- Moose::Util::TypeConstraints vs Moose::Meta::Type{Coercion,Constraint}
The Util module has _way_ too much functionality. It needs to be
refactored so it's a thin sugar layer on top of the meta API. As it
stands now, it does things like parse type names (and determine if
they're valid), manage the registry, and much more.
- Moose::Meta::Role::Application::*
These class names are hardcoded throughout Moose, making replacing
them very difficult.
- Moose::Meta::Role & attributes
The way a role stores attributes is nasty and not very
introspectable. It should store some sort of object, possibly one that
knows how to turn itself into a "real" attribute.
- Anything with a _(meta)?class method
Every method that returns a class name needs to become a rw attribute
that can be set via the constructor.
- The Moose::Error stuff
This is sort of half-implemented. We still use Carp directly, and the
internals can't decide how to throw an error (is it
Moose->throw_error, __PACKAGE__->throw_error, what?).
The internals need to be made consistent before we expose this to the
rest of the world.
- Moose "strict" mode
use Moose 'strict'; This would allow us to have all sort of expensive tests
which can be turned off in prod.
- Moose::Philosophy.pod
To explain Moose from a very high level
- moosedoc
We certainly have enough meta-information to make pretty complete POD docs.
