(if I correctly understand what he says) explaining why the other
options cannot be optimized. What he says sounds correct to me, it was
just my way of verifying it. Which is required for me, as I don't have a
copy of the C++ standard. Seems it's time to buy one... :-}

If this also counts as an argument: Scott Meyers mentions the same
scheme I propose in the errata of mec++ as the recommended
