 Trends
 ======
 
-Ubiquity
---------
-
-As always, [Perl is optimized for freedom and richness of
-expression](language-design.html).
-
-
-
-General Purpose
----------------
-
-Perl 5 still has a lot of builtins, showing for which task the
-language was created. But to become more general purpose, the core was
-enhanced and some other parts got removed. File IO, Network and IPC,
-Formats, and finally that long deprecated pre P5 DB-binding (dbmopen)
-went out of the core or at least into sensible module namespace. The
-optional type system enables compiler optimisations to make Perl even
-usable in cases where you had to switch to C before.
-
-
-
-Less Unix Centric
------------------
-
-Perl 1 was a child of the Unix world, borrowing a lot of folklore and
-words. As Perl 6 had to regularize the Regex and reform some other
-parts, this heritage has become less visible.
-
-
-
-Unicode
--------
-
-Per default all Perl 6 code is Unicode and you can use any weird
-character for any part of the syntax.
-
-
-
-Simple English
---------------
-
-In Perl 5 we had my, our, use, require, bless, can, ISA (is a), chop
-and also of course if, else, goto and all the loops. Perl 6 adds
-given, when, gather, take, loop, WHERE, HOW, WHO and lot more everyday
-English, which should make it easy to read and understand.
-
-
-
-Hidden Complexity
------------------
-
-Even simple Perl 6 looks pretty much like older Perl, it has a
-tremendous complexity inside, which only have to show up if you really
-need it.
-
-
-
-Functional Programming
-----------------------
-
-High order functions, currying, you name it. All that goodies are
-there, as Perl 6 aims to a full support of functional programming.
-
-
-
-Object Oriented
----------------
-
-OOP syntax is now more simplified, compact, knows about encapsulation
-and has many new features, including dynamic class composition.
-
-Like in Smalltalk or Ruby every "thing" (values, vars, blocks,
-routines) is an object and ops are "just" methods. It helps to have
-internally everything in its place. But programmer still can pretend
-it's not the case.
-
-
-
-Full Introspection
-------------------
-
-Because every object knows his attributes and methods, you can ask the
-compiler nearly anything about the state of your program.
-
-
-
-Metalanguage
-------------
-
-And because classes are made to get extended or changed, Perl 6 has
-not only full metaprogramming capabilities, beyond your wildest
-dreams. It is a metalanguage with a beginner friendly default that
-aims to become a family of languages. Rule of thumb: everything is
-allowed, as long as you declare it.
-
-
-
-One Spec - Many Implementations
--------------------------------
-
-Unlike every other Perl so far, Perl 6 has a precise specification,
-written in Perl 6. This allows to have several implementations, even
-syntactical compatible ones.
+The more general course of the changes
+[](tablet-1-language-design.html#trends)
+is written down in the language design tablet.
