A question if I may.

Why does D allow iteration over an interval of floats? A floating point
number has no direct successor or predecessor. Any such interval would
contain zero, one or infinite elements.

Given the -0.3, I'm assuming you increase/decrease by 1.0 each iteration. Is
this useful enough to be the standard behavior?
