It's not for smart pointers. It's for iterators. To do an iterator, you
need 4 operations:
1) copy
2) increment
3) compare for equality
4) get the value
The first 3 are already covered by operator overloading, so we need one
for the last. You could do these through member functions, but then you
couldn't use a pointer as an iterator.
