--- Comment #2 from moonlightsentinel at disroot.org ---
Possible reduction (but might also be another bug):

=====================================================

alias dgType() = extern(D) int delegate();

extern(C++) int cpp_set_foreach_ind()(dgType!() dg);

int foo(int delegate() dg)
{
    return cpp_set_foreach_ind!()(dg);
}

=====================================================
