Well in the example I gave, the type of class foo would genrally be
something like IronPython.NewTypes.System.Object_1$2. There's not going to
be any "native" CLR code to which you can pass a
List<IronPython.NewTypes.System.Object_1$2>, and if you're passing the data
to other Python code, you may as well do it as a Python list or tuple. It's
the "dynamic" thing to do :).
List<IronPython.NewTypes.System.Object_1$2> isn't even type-safe for Python
classes because IronPython maintains a cache of generated types and will
reuse a type it has previously generated for any new class you define that's
compatible with a previously-defined class.
