Re: [Spirit Qi %] (x%y) not semantically equivalent to (x >> *(y >> x))

Don't get me wrong, please. You actually do not need the % operator at all. As far as I understand it,  it is intended to be a way to express x >> *(y >> x) shorter and therefore more elegant. 

If that (and I actually just believe and not know that) was the intention to introduce an otherwise obsolete operator, this intention is missed. If they want you to use one for the other one must behave aus the other in any case. That's my notion of same sematics here. 

X % Y is not a fully featured replacement for X >> *( Y >> X). But once you know that, it's ok and you just drop % (until you find a case where it's special  behaviour is needed). Not ok for me at least is that each and any user has to find that out the hard way by trial and error that both Idioms are not the same. 

That's because you do not expect the reason of your problem to be right at this place. This is one of the last places to search.
