Summary: Can't assign to __name__ or __bases__

Initial Comment:
While it's rarely useful, there *are* situations where
assigning to __name__ or __bases__ of a class might
make sense.  So maybe this should be allowed.

e.g.
def mkclass(cname,something):
    class lcl:
        def __init__(self):
       ... yada...
        def f(self, parm = something):
         ... yada ...

   ... yada...
    lcl.__name__ = cname
    return lcl


My understanding is that this function returns a different
class object (each cut from the same cloth, as it were)
each time it is called, but they all have the same name
by default.
If you are doing this (which is a cool thing to be able to do)
it certainly makes sense to give each class a different
name.  I just tried this,  however, and it seems to work.
__name__ got changed, and instances have the new name
in their default repr().
