[Boost-users] Question about traversing mpl vectors

Let's say I've got some mpl::vector. If I grab a begin iterator on it, and increment that iterator past the elements in the vector, what happens? For instance: ================================================== using boost; typedef mpl::vector t; typedef mpl::begin<t>::type element0; // Should deref to 'int' typedef mpl::next<element0>::type element1; // Should deref to 'char' typedef mpl::next<element1>::type element2; // What happens? typedef mpl::next<element2>::type element3; // " typedef mpl::next<element3>::type element4; // " ================================================== Will boost let me iterate past the 'end' of an mpl::vector? Am I supposed to take care of bounds checking?
