I much prefer languages which simply do not make a distinction between functions and operators.
This distinction seems useful only in the context of lower-level languages like C where the operators translate directly to single machine code instructions and thus they provide clues about performance.
But in a higher-level language this distinction is superficial. It's just another function, just with a much shorter name and perhaps using infix instead of prefix notation. E.g. in Lisps there is no such distinction. "+" is a valid function name. In Haskell - same, but you also have a built-in syntax for specifying that you want your function to be called using infix notation by default.
