[Swift-devel] Foreach with floats

[Tim Armstrong]

Something like the following might be the easiest solution:

foreach i in [0:20] {
  float j = i * 0.5;
}

I think most languages avoid encouraging use of floats as loop variables
since its fairly easy to run into surprising behaviour with floating point
precision, depending on the way things are implemented.
