There was a problem hiding this comment.
This change in constraints is a non-breaking change since the AMP proposal went through (GHC 7.10?), but represents a breaking API change for earlier GHCs. I think it's better to only introduce the Functor/Applicative constraints conditionally for GHC 7.10 and newer.
