Let f be a variadic function:

Result f(...);

How to implement variadic function g which calls f with the same 
arguments as one it receives?

Result g(...) {
   // ...
}

I don’t know if you can, but if at least g is a variadic template 
function, you can:

If you must use C-style variadic arguments, then your only choice 
is to do it the same way you would in C: write a version of `g` 
that accepts a va_list (like vprintf(3)), and have `f` call that.
