"my brain hurts" or is isinstance broken?

i know that and i like it.

lets simply say: the requirement is exactly to destinguish between
instances and classes.

one could imagine an object that is a mix between a factory and
a prototyperegistry.

class ProtoFactory:
   def __init__(self):
      self.SourceObjects = {}
   def register(self, name, source):
      self.SourceObjects[name] = source
   def create(self, name):
      source = self.SourceObjects(name)
      if isinstance(source, types.Instance.Type):
         return copy.copy(source)
      else:
         return source()

this is just an example. i am sure, that this can be done
differently. the real reason why i want to do this is something
i realy dare not to say in this forum ;-)
just that i am realy realy nasty!
