("hello","world") & _1.traverse %~ toUpper & _2 .~ 42 ("HELLO",42)
could be written
_2 .~ 42 $ _1.traverse .~ toUpper $ ("hello","world")
Surely, you must be joking. That's some butt-ugly piece of code. Let's not try to turn Haskell into J or Perl. Personally, I like neither (&) nor (|>). The latter is used in OCaml/F# but looks quite ugly (I know rendering it as a latex triangle would look pretty nice, but we can't rely on everyone having that option). Regarding, (&) I agree that it looks a bit like bitwise or, but I suspect that is something that people can get used to quite quickly. I agree with Johan that "works well with <some-non-platform-library>" should not be a criterion. +0.2 for (&), and +0.1 for (|>)
