Or you could use the "subtract" function.
map (subtract 2) [3,4,5] [1,2,3]
I don't want to.
I don't think syntax sugar is worth it in this case.
I do. Operators are great because they make our intent visible, immediately apparent. Long words' meaning, like subtract's, is not immediately apparent, and they break consistency. Not everyone's first language in life was English, you see. (`foldl`2) works. (`-`2) should too. I'll settle for (+(-2)) for now, but it ain't that pretty.
