... Wouldn't it be nice if these were flagged at compile time! More work for Jeremy .

As will (or already has ) been pointed out, the compiler can only guess, and can't always guess right (it could err on the side of bothering you without cause, though). PyChecker goes a long way already. Java has a mass of "definite assignment" rules instead, which in effect decree that you must write code in such a way that the compiler can always guess right.
