That is available in Haskell, and I have used it a lot in Hugs.
But in ChucK, I just compute rationals directly into log2 intervals -
there isn't any need of true rational numbers if one just is going to
play the interval.

If one actually wants to scrap "/" for integers, the replacement would
be functions like div(), quot(), rem(), guaranteeing the remainder is
the correct range.
My biggest worry is having a load of numerical data that must be
edited by hand before entering, and forgetting quietly making
