I would like to formally propose that Monad become a subclass of Applicative, with a call for consensus by 1 February. The change is described on the wiki at http://haskell.org/haskellwiki/Functor-Applicative-Monad_Proposal,
That page isn't written as a proposal yet, it's written as a bunch of ideas. I would be happy to see something along the lines of Bas van Dijk's work http://permalink.gmane.org/gmane.comp.lang.haskell.libraries/14740 .
This is a proposal with far-reaching consequences, and with several alternative designs. I'm not sure I understand all the tradeoffs. Some parts of the proposal are orthogonal to the rest (e.g. changing fmap to map), and should probably be considered separately. Could someone please write a detailed proposal, enumerating all the pros and cons, and the rationale for this design compared to other designs? Cheers, Simon
