It would be a nice idea for a different language. Python's execution model
would have to be changed dramatically in order to support this (outside the
very narrow case of annotations or the cases where it already works). This
just isn't going to happen -- too much code relies on the existing
execution model.

I couldn't extract an actual proposal from the stackoverflow link you gave.
