I agree. Although I posted a solution a few days ago, mostly 
you just write the code such that you don't care what types 
get passed in. When you combine that with default arguments 
and keyword arguments there is hardly ever a real need for 
overloading.

Controlling a class explosion (which was Arthurs problem) is 
better handled by one or more class factories operating at 
the appropriate level of abstraction - shape say in his case...
