If I have a variadic function

f(Rs...)(Rs ranges)
{
    g(ranges);

that calls

g(Rs...)(Rs ranges)
{
    // use ranges
}

and all or some of the elements in `ranges` are non-copyable can I
somehow move them at the call of `g` inside of `f`.

I've tried

f(Rs...)(Rs ranges)
{
    import std.algorithm.mutation : move;
    g(move(ranges));
}

but that does't work.

At least compiles. :)

void f(Rs...)(Rs ranges)
{
    import std.functional: forward;
    g(forward!ranges);
}

void g(Rs...)(Rs ranges)
{
    // use ranges
}

struct S {
    @disable this(this);
}

void main() {
    f(1, S());
}
