I'm working on an implementation of that, by the
way, so it may be possible for people to try it
out soon.

I don't think it's helpful to jump on that particular
terminological detail. The people who ask "why is there
no += operator" aren't using the word "operator" in its
precise technical Python sense.

I'd say quite the opposite - this is a rare case in
Python where IMplicitness loses! If the distinction
between integer and floating point division were
made explicit, by having different operators for
them, this would cause much less grief.
