In a more realistic example, the current dollars help to improve readability, I think, and that is my argument why "$" should be right- associative:
map (+ 1) $ filter (/= 0) $ Set.toList l
An additional $ before the final argument (" $ l") looks stupid to me. I also find additional parentheses instead of the dollars more confusing, because of the other parts in parentheses.
If you don't like map (+ 1) . filter (/= 0) . Set.toList $ l then map (+ 1) . filter (/= 0) $ Set.toList l works just as well. In this case it's also a fairly natural way to break up the thought process. Your main computation is solely a composition of list functions, and the conversion is part of how you get the input to it. - Cale
