Hi, I used monads in two projects.
* The last rewrite of ClojureQL before v1.0 used a state monad to keep track of various things during query creation. * ClojureCheck also uses a monad approach to create and combine generators for test data. * Dave Ray and I tried a monad style in the async branch of seesaw. Both were custom monad implementations. Both work(ed) reasonably well. However things have a relatively high strangeness factor. Since the execution of things is deferred till someone actually runs the monad pipeline, you can't use your usual try/catch construct to take care of problems. Everything has to be constrained to your monadic function. So you need to have some way to error out of your monadic pipeline. This leads you to monad transformers and complicates things even more. In Clojure I haven't seen a use were other approaches weren't just as feasible or were monads would have simplified things. They are a legal approach, but I would judge on a case-by-base basis.
