[heading Exception Safety]
All of the variants of `all_of` and `all_of_equal` take their parameters by value or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee. It may be true, but it's not an appropriate conclusion from the premises. std::copy also takes all its parameters by value.
Good point - how would you state it, then? "Only reads from the iterators" is the key point (unlike std::copy)
Maybe because these functions don't modify anything? Vicente
