Using the current variadic functions makes it possible to use 0 or N
arguments, e.g.:

function sum() {
    return array_sum(func_get_args());
}

echo sum(10, 5); // echoes 15
echo sum(); // echoes 0

I see nowhere in the RFC whether:

function sum(...$params) { /* */ }

Requires at minimum one argument or none.

I have the _feeling_ that you imply it's minimum one which I would
consider a bit inconsistent with the current "implementation".

Can you please clarify this Nikita?

Thanks
