[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<int, char> 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?

Thanks,
