           Summary: Cannot declare ref parameter of opaque type
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor

Functions cannot accept opaque types by ref (pointer and slices work already):

----------------------------------------
struct Opaque;

void byPtr(Opaque*) {}
void byRef(ref Opaque) {} // Fails
void bySlice(Opaque[]) {}
----------------------------------------
