This is quite neat.  I only skimmed the module a bit.  any reason the 
::declare modules isn't using object::declare?

A bit related to this particular abstraction, I was thinking the 
classloader should mostly only inject 'use base' and some very short subs:

   requiring 'Some::**::Class' => generates { qq{
       sub print_my_middle_names { print $1,"\n" }
   } };

can be:

   requiring 'Some::**::Class' =>
     base is 'YourBase',
     method print_my_middle_name => sub { ... },
     more_code is { qq{sub still_able_to_declare() { } } };

This also avoids string evals and gets us more compile time check.

should really be
