Subject: Freeze, objects, crash, boom.

I've been trying to wrap my head around freezing and objects. My current understanding is that:

o parrotclass extends delegate

o delegate's freeze vtable entry is Parrot_delegate_freeze

o Parrot_delegate_freeze should delegate the freeze vtable method to PASM.

However, when parrotclass.pmc is compiled to .c, its vtable method for freeze is NOT Parrot_delegate_freeze, but Parrot_default_freeze.

This makes me think that something in pmc2c2.pl isn't quite right, and digging in there, I see:

            # XXX this is a quick hack to get the inheritance
            # ParrotClass isa delegate
            # ...

Are any of my assumptions here correct? Is this chunk of pmc2c2.pl the right place to look for implementing a fix?
