Fixing the MDbg / Iron Python extension...

A while ago, we had a sample of Mdbg-Python extension that let you use python to script MDbg. It was based off a pre-release Iron Python, and things have since broken. We updated at least once to keep up with the breaks. We're aware of the problems and

Why doesn't MDbg use generics?

If you've looked at the MDbg sources, you'll notice it looks a lot like a V1.1 app. There are few to no V2 (Whidbey) concepts in there: few anonymous delegates, very little (if any?) generics, no 'yield' keyword. Since MDbg shipped in V2, why didn't we
