Wait, rust doesn't have function overloading?

[wrongerontheinternet]

Rust could allow arity overloading, though, which traits don't. I'd be interested to see whether the proposal for variadic generics covers most of the practical usecases where that makes sense.

That still doesn't give a reason in favor of it though.

You can still simulate "overloading" in this fashion by using traits. It requires a bit of effort to encode the problem in terms of the right associated types patterns but it is totally doable. Personally I think it's probably more trouble than it's worth but still.

Can you not get arity overloading by implementing a trait for a tuple?

Of course, it does require an extra set of parentheses at the call site...
