That's not a very Haskell thing to see that many Unicode operators. Are you thinking Agda or APL? At least in PureScript, all infix operators must have word name and is either a list of ASCII symbols or a single Unicode character. And even still, you see a massive amount of programmers abusing (and misusing) ligature fonts to make their code look more like math without embracing Unicode and the actual symbols. Why fight over composition operator being `.` or `<<` or `<<<` when you can use the one from math, `∘`? Using Vim, use the digraph `Ctrl+k` then `Ob` and now you have a `∘`.
