Summary: new module broken with new classes

Initial Comment:
The new module doesn't support the new-style classes.
Example:

  import new
  class foo(object):
      pass

  a = new.instance(foo,{})

I didn't really expect this to work, but I'm trying to
figure out how to emulate the behavior of this function
with new-style classes (i.e., how to bring a new-style
instance into being without calling __init__).

Does a call to PyType_GenericAlloc(PyTypeObject *type,
1) emulate this behavior?  Please advise.

Cheers,

Dave

Doesn't

  a = foo.__new__(foo)
  a.__dict__.update(dict)

do this?
