well, pickle just saves them as a global name (modulename.classname).
so types would generally just return themselves as primitives, and let
the actual simplifier do the trick.

it may choose to save the type's dict, or just a global name.
that's up to the serializer-dependent simplifier.

it's good you mentioned that, because it reminded me of something
i forgot. for instance, code objects will be serialized by value,
so you could actually pickle functions and classes.

this means pyc files could become just a pickle of the module, i.e.:
   import foo
   pickle.dump(foo, open("foo.pyc", "w"))

but again, that's up to the serializer. an enhanced pickle could do
that.
