As an aside, the integers form two different monoids. Haskell can't [easily] handle that. Does anybody know of a language that can?

Some of the ML-derived languages can do that. Essentially, your code takes another module which implements a monoid as an argument. The catch is that you have to explicitly provide the monoid implementation in order to use your code. -- Dave Menendez <dave@zednenem.com> <http://www.eyrie.org/~zednenem/>
