Could this also be used to make vector<Derived> implicitly convertible to
vector<Base>? It seems so if everything is implemented in terms of char* and
the only difference is the increment (of char) to move from one element to the
next. Of course I guess this would mean the increment op would have to be virtual,
but maybe not. If the iterator, as suggested above, the increment size was parameterized,
this would eliminate the need for virtual increment.
