My knowledge of functional programming is pretty much limited to Haskell, Scheme, and a smattering of Common Lisp. Are there languages other than Haskell that explicitly use monads? How about "not so explicitly"?

Yes, there are plenty. But none of them capture it quite as well as Haskell, IMHO, because the Haskell overloading makes it look particularly nice and succinct. And the second question about "not so explicitly", you could say that any language uses an implicit monad. It's where you throw in all the effects. -- Lennart
