Your right. ( It wouldn't ! :-)

Since Python doesn't have multi-methods, I don't thing they make sense
as the solution for operator typing and coercion. Operators aren't
*THAT* special case - that's why overloading works. So if you are
going to provide multi-methods, you should provide them generally,
which would be a major shift for Python.

But this thread demonstrates why multi-methods are a good idea in
THEORY, so if you want to submit an experimental implementation, I'll
be happy to play around with it! ( But I suspect that actually using
it would be very awkward in a language that was not _built_ around the
idea or had some support for signature analysis, etc. )
