Well shoot, if that's the objection, then put it in the standard
distribution! :)

The problem is that Python provides no way for an add-on module to
define new operators.  It's thus impossible to provide appropriate
notation *without* making it part of the language.  If there were some
way to define, in the module, how to interpret specific new operators,
that should be adequate -- but that seems like a *far* more difficult
solution than what's needed here.

Unfortunately, the current lack of appropriate notation makes these
problems very difficult to code clearly.
