I never said this, but I thought about it in order to limit the speed penalty.

But using two variables is somehow sabotaging the intent of nicer code....

I'm not sure about if the performance penalty for tied variables also hits if FETCH was not altered, but I think it's very likely so.

An XS implementation might levitate this, not sure which kinds of "magic" are possible here.
