[Ifeffit] formula checking

Hello all, I've got a quick question about the checking of formulas. I mistakenly typed "//" instead of "/" into several 'def' commands in my model. Unfortunately it took me a long time to find the mistake, since it was a complex model and by some fluke the equation gave almost (but not quite) the expected value. Since "//" doesn't seem to be a valid Ifeffit operator, why didn't either Ifeffit or Artemis pick it up?
