Some languages and uses for monads

According to you, which language do you 开发者_C百科think would be the best for implementing monads (Python/Ruby/LISP)?,also can anyone tell me some possible uses of monads (please give examples),like exceptions?

Thanks in advance

All About Monads - legendary tutorial that lists all the standard monads and gives a lot of real-world examples.

Popular monads that you can meet even in the mainstream languages are Maybe, List and Continuation. Some people also think that jQuery itself is a monad (as it follows the monadic axioms).

As for the language choice, Haskell and its derivatives are using monads as a fundamental concept, however, as an option, constructing monads is possible in a lot of modern languages. In order to familiarize with the monad concept I'd better choose the language I'm the most comfortable with.

In order of preference:

1. Haskell
2. F#
3. Scala
4. C#

Monads in order of decreasing simplicity:

1. Maybe (Exception)
2. Reader
3. Writer
4. State
5. Parser
6. Async

Here are some tutorial that use clojure. Monads are implemented in a library.
