Why doesn't a sealed range offer references? Is it to prevent
modifying the elements being iterated?
(I searched google and TDPL but couldn't find any info on sealed ranges)
Because a sealed range then has complete power over memory allocation of
its elements (really, I think sealed ranges is a misnomer, it's really
ranges on sealed containers).
Ah, my mistake. I thought sealed ranges were simply ranges that did not
allow modifying the underlying container (a "logical const" range), and
similarly for sealed containers (= an unmodifiable container).
I see why escaping references is not allowed then.
