Interesting that Haskell goes in so hard for operator overloading. In other languages I've used, while you can overload a bunch of operators, it's not a common thing to encounter, outside of math code, where it makes the most sense. Technically you could do all sorts of crazy operators in C++, but that tends to be frowned upon in that community.
It's not operator overloading. It's using symbols as function names. Some operators like (<>) may have different implementations based on the Monoid instance of the underlying types, but they are based on laws which is different from say Python where >> can mean anything based on the context (even though it is used sparingly there).
