You are trying to apply C++ and C# thinking to Python. This is a
fundamental philosophical difference between the languages. Python
doesn't care what the object IS. Python only cares what it EXPOSES. If
it has a GetName() method, you can call it, no matter what the object
ancestry was. -- tim

IronPython] .NET casts in IronPython
Why do you need to cast to the base class? All of the members you need should
already be there.

I need to cast a .NET object A to a .NET object B. There is nothing tricky
about the cast, it's a straightforward cast to a base type. How can I do this
in IP?
Thanks!
