[picocontainer-dev] Interception (behavior factory) and Intercepted (behavior)

Added 15 mins ago.

Pre & Post interception

You can intercept a method call before it is invoked (and optionally  
veto its invocation, with an alternate return value).
You have a call another interceptor after the method has been invoked  
(and optionally override the return value).

Limitations

Can only do this to interface/impl separated components.
Will (likely) break if there's deep recursion into Intercepted  
components.
Can't modify arguments being passed in to method.
Can't paricipate in instantiation (no pre or post for Ctors).
Can't play with or intercept fields on component.

Thoughts?
