[Python.NET] Dynamic types of returns PyObject from the runtime

[Barton]

python dynamically typed: Yes
C# dynamically typed: No, strongly typed. It uses lots of overloads to 
return the required type.
I suppose some embedder somewhere has a neat way of applying the type 
info on the PyObject to some sort of wrapper.

What language is that, anyway? It looks sort of interesting.
