On a related note I've wondered about this:
>>> class Foo(object): pass
>>> f = Foo()
>>> s = repr(f)
>>> s
'<__main__.Foo object at 0x007CBAB0>'

So how do I get f back from s ?
Obviously this is open to abuse. I just wondered if a mechanism existed short of writing
a C-extension which parses that string, casts the hex number to a PyObject *, INCREFs it,
and gives it back...
