[IronPython] CodeContext went from language-independent to IronPython-specific

Thanks, Tomas and Curt. I see your blogs on this topic.

Let's say I wanted to use the DynamicObject approach, and I have a dynamic
C# object with a runtime member called SomeMember. Let's say SomeMember is a
.NET List, but I want the object to return a calling-language-specific list
type. How could I perform a language-specific conversion?

In other words, with my scriptable application, I might want to better
support the scriptwriter's language by returning language-specific types. If
a scriptwriter is using Python, it would be nice to return a Python list for
SomeMember. If the scriptwriter is using Ruby, it would be nice to return a
Ruby list.

If there was some way to get access to a type converter based on the
"calling context", this might be doable.

Does that make sense?
