At least in F#, I think that having too much need for arity overloading might be considered a code smell. In a nutshell, the idea is that, if you've got a bunch of functions with the same name but different arities, collectively they add up to a violation of the single responsibility principle. If you do need it, though, you can make a 1-arity function whose only argument is a tuple of a given size. This is how methods from C# and VB libraries are presented. I believe that it just compiles to a non-curried function behind the scenes.
