prompt (hackage): Monad (and transformer) for delayed-effect "pure" prompt-and-response queries.  Allows you to specify programs that might query a database, talk to stdio, etc., without ever involving IO or opening the door to arbitrary IO.  Write a potentially pure computation describing prompting interactions, etc., without having your type actually do any IO or involve itself with IO or any effectful context.  Useful as a source of "things from IO", without ever actually involving IO or arbitrary IO itself; only executing a specific subset of IO (or State, etc.) that you yourself, the caller, specifies explicitly.  Safer and more meaningful type.  For more information and instructions on usage with examples, see the README.  Not quite related to the MonadPrompt library.
