If the pointer would be guaranteed to be nonzero, I would prefer to use
a reference (in the function signature) instead of a pointer. I admit
that it's not always possible to use references, because pointer
arithmetic is not applicable to references. But in this case, an
iterator would be more suitable than a pointer.
