Generalizing map?

Earlier versions of the haskell standard originally named fmap map.  It was
only as of haskell 1.4 or so that what was then map got renamed to map

I think the only technical objection is making sure that theres no
performance regressions wrt applicable fusion opportunities.

Subject to that, hearty plus one to fmap reclaiming map :)
> Although I would prefer the far more radical (and thus far more
unlikely to ever happen) approach of actually renaming 'fmap' to 'map'.

I'd vote for that too.
