I answered my own question by reading this monad-prompt example: http://paste.lisp.org/display/53766

But one issue remains: those examples show how to make play EITHER a human or an AI. I don't see how to make a human player and an AI play SEQUENTIALLY (to a TicTacToe, for instance).

Make them polymorphic - the human player in any MonadIO, the AI player in any monad. Then run them both in the same monad, with some kind of wrapping function around the calls setting a context for the appropriate player. -- flippa@flippac.org
