Summary: inspect.isclass() fails with custom __getattr__
Initial Comment:
inspect.isclass() can return True for instances of classes
which define a __getattr__ method. For example:
>>> class Namespace(unicode):
... def __getattr__(self, attr):
... return '<%s>' % (self + attr)
...
>>> inspect.isclass(Namespace('foo'))
True
Changing inspect.isclass() to:
return isinstance(object, (types.ClassType, type))
solves this issue.
The check for __bases__ is no longer need due to
type/class unification.
