STL iterators can be used for more than just iteration. They also
serve as cursors, or pointers to specific elements. If you add the
ability for them to check their own bounds, then they become as safe
as ranges, and can be used as general purpose pointers for things like
insertion, deletion, bi-directional traversal, things that ranges can
do but are clumsy at.
You still have the interchangable-with-pointer concept burned into
your brain :)
Think more like this:
for(cursor i = begin; !i.end; i++)
So basically your cursor is a range (so it knows its bounds) with an
added position pointer.
Basically, yes.
