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. :)
