Ongoing maintainence of large software projects is much more expensive than creating the software in the first place, and anything which makes it more difficult to understand code that you wrote two years ago is a Bad Thing. Secondly, there is a performance penalty in doing things this way. I tested the incremental step size method (add step_size to step_var) versus this modulo method and found that the modulo method was 4.5 times slower. (If anyone wants the source code for this, please email me.) Of course, in a real life example, the time taken by the repeat loop itself will be incidental to the processing time done in the loop, so the difference may not worry you.
