import std.variant;
import std.stdio;

Variant a;

int mul2(Variant b){
    int c = *b.peek!(int);
    return 2*c;
}

int mul3(int b){
    return 3*b;
}

void main()
{
    a = 5;
    writeln(mul2(a));

    Variant b = 3;
    writeln(mul3(*b.peek!int));
}

Uh, probably this is not what you want. I found this thread: https://forum.dlang.org/thread/ebylgcrslkelgrvnt...@forum.dlang.org

You man need to use Algebraic.
