Summary: im_func, user-defined method

Initial Comment:
>From the language reference:

3.2 The standard type hierarchy 

User-defined methods:

A user-defined method object combines a class, a class 
instance (or None) and a user-defined function.
...

I take issue with 'user-defined function'.  In my 
experiments with Python 2.1.1 on Windows 2000, using 
the C API, a user-defined method can combine a 'user-
defined function' OR a 'builtin function'.

I call PyObject_GetAttrString( pPyObject, "im_func" ), 
and a built-in function type object is returned.

Tom.

Fixed in Doc/ref/ref3.tex revision 1.71.

The manual used to be right, but more flexibility was added.
 Normal usage still only finds user-defined functions there,
but the exceptions module uses built-in functions, and the
"new" module can be used to construct more interesting
objects as well.
