I think you are missing the point of what happens if the step is not 1

the passed in type can have fractional input). EG:
iota(0, 105, 10);
or
iota(0, 10.5);
In this case, "back" should be 100, and not 95. To compute back, you
need to be
able to evaluate length, and to add length*inc to front.
Oh, snap. Have we been working on the same problems for too long? :-)
The integral cases are easy. We need to crack the floating point case:
given numbers low, up, and step, what's the closest number smaller than
up that's reached by repeated adds of step to low?
