I do not have need for such a class right now, as I just play the  
intervals, and therefore floats are just fine.

Though I have written Haskell code for computing continued fraction  
convergents, which is very useful for analyzing data, which I use in  
Hugs. So rational numbers are useful - I just don't use them in ChucK,  
right now.

But you bring up a question of where to put the stuff. Putting it up  
on this list is just convenient for snippets really.

Check out <http://haskell.org/>. It is a wiki, I think. One can search  
a lot of code there. Perhaps there should be something for ChucK.
