Huh? Perhaps you meant "for ("hello") vs. ("hello", "world")"? Because it would be the same instantiation for a single string argument :)

You're right. I mistakenly assumed it would be the same as RandomChoice(string a, string b)(). But still, as you show, the instantiations could be too many for R...

I am still wrong there. It is inconceivable to instantiate the following template for the same type (e.g. string) from "too many" places in a program:

auto RandomChoice(R...)(R r) {
  // ...
}

There may be a few instantiations that call it with 1, 2, 4... maybe 10 arguments? But that would be it... Oh! Unless there is some code generation. :)
