Moose

Changes for version 0.19

~~ More documentation updates ~~
Moose::Util::TypeConstraints
- 'type' now supports messages as well thanks to phaylon for finding this
  - added tests for this
- added &list_all_type_constraints and &list_all_builtin_type_constraints functions to facilitate introspection.
Moose::Meta::Attribute
- fixed regexp 'handles' declarations to build the list of delegated methods correctly (and not override important things like &new) thanks to ashleyb for finding this
  - added tests and docs for this
- added the 'documentation' attributes so that you can actually document your attributes and inspect them through the meta-object.
  - added tests and docs for this
Moose::Meta::Class
- when loading custom attribute metaclasses it will first look in for the class in the Moose::Meta::Attribute::Custom::$name, and then default to just loading $name.
  - added tests and docs for this
Moose::Meta::TypeConstraint
- type constraints now stringify to their names.
  - added test for this
misc.
- added tests to assure we work with Module::Refresh
- added stricter test skip logic in the Moose POOP test, ask Rob Kinyon why.
  - *cough* DBM::Deep 1.0 backwards compatability sucks *cough* ;)

!! You must have Class::MOP 0.37_001 !! !! for this developer release to work !!
This release was primarily adding the immutable feature to Moose. An immutable class is one which you promise not to alter. When you set the class as immutable it will perform various bits of memoization and inline certain part of the code (constructors, destructors and accessors). This minimizes (and in some cases totally eliminates) one of Moose's biggest performance hits. This feature is not on by default, and is 100% optional. It has several configurable bits as well, so you can pick and choose to your specific needs.
The changes involved in this were fairly wide and highly specific, but 100% backwards compatible, so I am not going to enumerate them here. If you are truely interested in what was changed, please do a diff :)
