Rather painful, I'm afraid. Mostly as there already is an "end()"
function with different semantics.
Also be aware that the two vector notions are completely different.
While one is a container used to store arbitrary objects, the other is a
mathematical entity. Having iterators over the latter doesn't feel very
natural to me. (The same way I'm not asking for a scalar multiplication
operator for std::vector)
But, as others wrote, if you really want them you can still have them if
you use pointers to the data.
