Overload the __or__ special function (ie the 'pipe' operator) instead of the
__gt__ operator.

I remember I have seen such a proposition (mentioning pump, filters and
sinks) but I couldn't find it in google.groups.com --I think Aahz had
something to do with it, but ICBW.

Ah, I found it:

I don't know why I remembered Aahz about it :)
