While it isn't exactly the same thing, OCaml requires you to use different operators (e.g. + vs. +.) for ints and floating point numbers, and it's a very common complaint about the language. (It has conventional precedence.) When conventional arithmetic doesn't "just work", languages will often give a first impression of being awkward, even though the rules of operator precedence are actually more complicated than just consistently using prefix or infix left-to-right.
