Summary: provides Moose-like method modifiers
Description:
Method modifiers are a convenient feature from the CLOS (Common Lisp Object System) world. In its most basic form, a method modifier is just a method that calls `$self->SUPER::foo(@_)'. I for one have trouble remembering that exact invocation, so my classes seldom re-dispatch to their base classes. Very bad! `Class::Method::Modifiers' provides three modifiers: `before', `around', and `after'. `before' and `after' are run just before and after the method they modify, but can not really affect that original method. `around' is run in place of the original method, with a hook to easily call that original method. See the `MODIFIERS' section for more details on how the particular modifiers work. One clear benefit of using `Class::Method::Modifiers' is that you can define multiple modifiers in a single namespace. These separate modifiers don't need to know about each other. This makes top-down design easy. Have a base class that provides the skeleton methods of each operation, and have plugins modify those methods to flesh out the specifics. Parent classes need not know about `Class::Method::Modifiers'. This means you should be able to modify methods in *any* subclass. See the Term::VT102::ZeroBased manpage for an example of subclassing with CMM. In short, `Class::Method::Modifiers' solves the problem of making sure you call `$self->SUPER::foo(@_)', and provides a cleaner interface for it. As of version 1.00, `Class::Method::Modifiers' is faster in some cases than the Moose manpage. See `benchmark/method_modifiers.pl' in the the Moose manpage distribution.
