[IronPython] Issue reading an InternalDictionary, Overloads fails with 2147483647 arguments bug.

[Dino Viehland]

Sounds like Action[Avatar] is working then - it's just that the lambda isn't doing
anything that you can see.  If you change it to:

l = []
temp.ForEach.Overloads[Action[Avatar]](lambda x: l.append(x.FirstName))

Then l should be populated with all the first names you're called with.
