I'd say in python this is def f(*arg) and def f(**dict), or not?

Probably I need the "params object[]"-approach, because I'll use the 
argument's name and not index.

The question is, how a PythonFunction can be casted to a delegate of a 
certain type or if that is not possible, how can the PythonFunction be 
called from C#?
