Nobody mentioned the most obvious example - the language which is most
similar to Haskell, but whose authors simply prefer a bit lowel-level
mechanisms, although monads *can* be used as well - if you wish.

Such Haskell-implemented monads as list/nondeterminism or Maybe, go without
any changements. State/IO use the unique types.
