Readers of this thread might be interested in my article and library for
multiple dispatch in Python:

While a given name is still only defined once, it is possible to control
the code called based on the type and number of its arguments.

Take it or leave it... it may not be the best approach to Koenig's
concern.  But maybe something to consider.
