Summary: pprint.pformat requires __repr__

Initial Comment:
Not having a __repr__ attribute seem to cause problems for:

    pprint.pformat

in Python 2.4.  This problem goes away when I use a Zope instance for 
Python 2.3.

The error message is generated when I try to access a private
workspace in the CPS interface.

I inserted a bit of debugging code, and I've attached a file that
contains the debugging print-out of the data that caused the error
and also the traceback.

I'm using:

    CPS-3.2.1
    Zope-2.7.3-0
    Python 2.4b2 built from source

on Linux.

I've attached a file containing a bit of debugging information and also 
the traceback.

Dave

This problem affects matplotlib still.  Here is a short example:

import pprint
from matplotlib.transforms import unit_bbox
b = unit_bbox()
pprint.pformat(b)

This should be fixed in pprint.py 1.31 in current CVS. Thanks 
for the report.
