Ahh, I am happy to have misunderstood. The "intuitively" threw me,
because I thought that was building up to a "but", and misread the
rest.

I then react stronly, because I've seen so much total crap (the
type-based C aliasing rules topping my list) etc coming out of
standards groups because it allows them to generate wrong code that
goes faster, that I just assume compiler people are out to do stupid
things in the name of "..but the standard allows it".
