I'm genuinely interested (not being snarky, honest) - could you explain why you think that expression has anything to do with multimethods? Like I said previously, I'm new to Python and I'm curious what that expression actually means.

You can override the behavior of a function based on the types involved. For instance ``coerce(a, b)`` calls ``a.__coerce__(b)``. By overriding ``__coerce__`` for one type you can customize this.

Do you then have to have conditional code in a.__coerce__(b) to check the type of b and do the appropriate thing?

Basically yes. Although there are ways around it: http://www.artima.com/weblogs/viewpost.jsp?thread=101605

Thanks - that looks quite neat.

It seems to me there is a big difference between having a language that is truly based on multimethods and one where it is possible to implement multimethods fairly easily - from what I can see Python looks more like the latter.
