-1 Over time, I've gotten feedback about these and other itertools recipes. No one has objected to the True/False return values in those recipes or in Guido's version. Guido's version matches the normal expectation of any/all being a predicate. Also, it avoids the kind of errors/confusion that people currently experience with Python's unique implementation of "and" and "or". Returning the last element is not evil; it's just weird, unexpected, and non-obvious. Resist the urge to get tricky with this one.
