Michael was just underlining the semi-random sequence lengths you will get
when using decimal floating-point representations. If you're aware of that
and it doesn't matter, then it doesn't matter :-) In integer-land one would
expect that len(range(x, i, y)) == len(range(10*x, 10*i, 10*y)) for all x, i
and y. This clearly wouldn't be true for frange().
