I have frequently felt that range(start=5, stop=27, step=2) reads better than
range(5, 27, 2), but not better *enough* to bother requesting a change,
particular given the conservative nature of the Python devs to such minor
interface changes (and rightly so).
If it came to a vote, I'd vote 0 on the status quo, +0 to allow all three
arguments to be optionally given by keyword, and -1 for singling step out as
the only one that can be a keyword. That's just silly (sorry Gregory!) -- can
you imagine explaining to a beginner why they can write range(0, 50, 2) or
range(0, 50, step=2) but not range(0, stop=50, step=2)?
