This is what I'm after for Python. The "only" problem is defining
the input and output types of functions -- the programmer will have
to provide this information somehow and in some format and
I'm not really sure which road to follow here (e.g. home grown,
ZSI type object style, XML Schema lookalike...). 

This gets particularly interesting when you try to model Python's
notion of interfaces onto the definition, e.g. first
parameter needs to be a sequence, second a number, third
should provide a mapping interface, etc...

Oh yes, and whatever the format will be, it'll have to provide
enough information to be able to generate SOAP type declarations,
WSDL type declarations, type check XML-RPC requests, and so on.

I'll keep on dreaming...
