That's awesome! My personal opinion; lambdas in Python are really limited relative to their potential. We should be better able to exploit the contrast between "a lambda is an expression" and "a def function is a statement." It would be cool if they could be modified just like classes, I think - keep the original lambdas, and add something else nice like Haskell's Arrows.
