Also, I was wondering if something akin to a "parallel or" exists. By this, I mean I am looking for a function which, given x : a , y : a, returns either, whichever computation returns first. Can I use strategies to code up something like this? I suppose this doesn't play nicely with the idea of determinism, but thought it might be worth asking anyway.

There is in fact a package that seems to do exactly that; look up "unamb" (short for "unambiguous choice") on Hackage. Cheers, Greg
