Well, I basically went "fuck this" after looking at Haskell for a while, but there's surfaced some links in the comments (thanks, akavel) and they provide some examples: >>=, >>, >, <$>, <$, <>, $, ., !!, !, <|>, :, ::, \, @, ~, -<, <-, =>, -> Taken together the syntax makes no effort whatsoever to be self-explanatory. I could handle it if it was the only programming language I would ever use, but in the polyglot world we live in and with my leaky bucket of a long-term memory this is not good enough.

I see what you mean. Most of these are custom operators which happen to be in the stdlib, but I wouldn't say :: or ->, for instance, should feel particularly mysterious with a bit of practice.

bind, ??, more than, fmap, ??, monoid, f $ x f(x), f . g . x == f(g(x)), x !! 1 == x[1], seq, ??... and \ is lambda.
