Well, if it we're a means of getting responses for methods you don't know of it would be nice - most people that go around breaking it simply implement their own (see Class::Classless - i just submitted a patch (phew, a whole one line) for it to return code refs instead of 1, and Class::Object - i trust the documentation).

The problem is that @ISA is not used, or perl's builtin method calling system is extended. That's the showstopper.

Provided Autoload would provide (and export) a can, which either returns an anonymous subroutine that takes care of things, or actually loads the sub and returns a subroutine ref to that, It should pose no problem at all.
