I've not been doing Haskell for that long, and I'm still very much a beginner, but so far, I'm not finding the community use of random ASCII for operator-like functions too overwhelming.

Also, I think one crucial thing is that the strictness of usage, enforced by the compiler, can help ensure that the code is used in the right way. I would feel a lot less safe doing it with Python for example (what I use day-to-day).

Also, Haskell has unicode source files, so there's even more scope, and it can lead to some funny results: https://hackage.haskell.org/package/acme-lookofdisapproval
