--- Comment #1 from moonlightsentinel at disroot.org ---
Overloading w.r.t. @nogc works since 2.080.1.

Test case:


struct Foo
{
    int[3] arr = [1, 2, 3];

    int opApply(scope int delegate(ref int) @nogc loopBody) @nogc
    {
        foreach(a; arr)
            loopBody(a);
        return 0;
    }

    int opApply(scope int delegate(ref int) loopBody)
    {
        foreach(a; arr)
            loopBody(a);
        return 0;
    }
}

void main() @nogc
{
    Foo foo;
    int sum = 0;
    foreach(f; foo)
    {
        sum += f;
    }
}
