Or maybe a ptr_vector, so that your iterators are automatically indirect?

lambda needs result deduction, which is hard, but you could always
write your own simple dereferencing functor along the lines of the
following:
template <typename T>
struct dereference_as {
    template <typename P>
    T &operator()(P ptr) {
        return *ptr;
    }
}

and then
for_each( aVector.begin(), aVector.end(), bind(&myFunc, bind(
dereference_as<A>(), _1) ) );
