I'm *not* discussing PEP 308, since that's supposed to
be happening on c.l.py. The operator names have been
changed to protect the innocent. :-)

Why is that any different from the following set, which
are already three different expressions in Python?

  ( bunch_of_grapes <   banana ) < pointed_stick
    bunch_of_grapes < ( banana   < pointed_stick )
    bunch_of_grapes <   banana   < pointed_stick
