A default of start=0 makes sense for integer range, because the most common use for range *by far* is for counting, and in Python we count 0, 1, 2, ... Similarly, we usually count every item, so a default step of 1 is useful. But for numeric work, neither of those defaults are useful. This proposed spread/frange/whatever function will be used for generating a sequence of equally spaced numbers, and not for counting. A starting value of 0.0 is generally no more special than any other starting value. There is no good reason to single out default start=0. Likewise a step-size of 1.0 is also arbitrary. It isn't useful to hammer the square peg of numeric ranges into the round hole of integer counts. We should not try to force this float range to use the same API as builtin range. (In hindsight, it is a shame that range is called "range" instead of "count". itertools got the name right.) -- Steven
