As for creating and dereferencing references; without seeing the

I wouldn't mind if implementing interface methods required `override` as

I just need an even/odd functionality. Don't think D has a
built-in operator.

return !(num & 1);

Perfect. That was the "essence" of my question. But thanks to

That can't work because there is no information to infer the type of
