[Python-Dev] pprint(iterator)

I quite like the idea of something along those lines. For example:

try:
  itr = iter(obj)
except TypeError:
  pass
else:
  return "<iterable %s: %s>" % (obj.__class__.__name__,
                                <as for list contents>))

Doing this only in pprint also reduces the chances of accidentally
consuming an iterator (which was a reasonable objection when I suggested
changing the __str__ implementation on some of the standard iterators
some time ago).

Cheers,
Nick.
