[IronPython] custom ConfigurationSection in IronPython

Ahh, you're right - currently it looks like we won't ever get non-public indexers (this one is family or assembly, which is "protected internal" in C# speak). This is a bug, I've opened CodePlex bug #2766 for this (http://www.codeplex.com/WorkItem/List.aspx?ProjectName=IronPython).
A simple workaround would be to write a class in C# that derives from this and exposes these publicly, and then use that class from IronPython.

Thats what I thought, but it doesn't work. And if I do dir() on ConfigurationElement I don't see a __getitem__ or __setitem__, though with other .NET classes that have the Item property I do.
