Re: [Doubt] Variadic arguments as reference (Possible?)

[bearophile]

MattCoder:

I want to know if there is a way to pass variadic arguments as reference? DMD says no!

I wrote the snippet code below, but what I want to do in fact is assign the sum back to respective variables to use somewhere else.

One way to do it, but beware of template bloat:

import std.stdio;

void sum(TArgs...)(double value, ref TArgs numbers) {
    foreach (ref num; numbers) // Note: this is a static foreach.
        num += value;
}

void main() {
        auto a = 1, b = 2, c = 3;

    writeln(a, " ", b, " ", c);
        sum(10, a, b, c);
        writeln(a, " ", b, " ", c);
}


Bye,
