I was thinking more of a feature I could call explicitly at runtime than 
something baked into the interfaces, rather than a new feature for makepy.

The problem is it can be inconvienent or impossible to figure out what 
constructor is appropriate. I'm thinking of something more dynamic where 
I don't tell it what to do, I just tell it: "figure out what class you are."
