>Because exceptions are a fundamental control-flow mechanism in Python (unlike in C++, where they should only be used for exceptional control flow), I'm not sure if there will be a net benefit to "zero cost" exceptions.
Well, they might be "a fundamental control-flow mechanism" but for every StopIteration (for an example of a control flow exception use), there are multiple (up to millions) of traversed elements that didn't throw an exception.
