Problem: enumerate elements from two parallel containers (aka
zipping).

Even with a single container an iterator is more flexible than an
enumeration operation if the iteration logic is more involved than a
single pass over the whole. Like iterate from the beginning until you
find some specific value. Or get top 10 from a sorted container. And
so on.

Which might mean that the concept of pointers is not completely
missing the point (pun intended).
