A couple more words to clarify my opinion ("La nuit porte conseil" -
nighttime brings advice).
The issue with pointers is that you always have to ask who owns the
pointed-to object. Consequences are double deletions bugs and memory
leaks. As opposed to C, C++ allows to write code with very few
pointers, and even better to encapsulate their use inside objects
(which is not the case here).
Iterators look like pointers for legacy reasons, but they don't need
to be pointers, and moreover no programmer ever asks himself if he has
to delete iterators (!).
