First solution: Don't do this. Type checking is bad.

Why do you have to do this? Could you give an example?

>>> isinstance(1, ObjectType)
1

And in case you hadn't noticed:

>>> ObjectType is object

What is it you want to detect with your type checking? Whether
something is an "object" or not is pretty meaningless with new-style
classes... (Everything is.)
