Yes, as far as this example shows.  I haven't look at other examples;
however, I've coded this range idea myself just using something
derived from pair<iterator,iterator>.  There's was something
already in boost that had ranges; however, I couldn't use it for
some reason.  I've also seen ranges coded elsewhere (in the polaris
compiler at uiuc).  If it's occurring so often, maybe it's worth
having a library.

Also, could someone tell me the reason for having, I believe
Thorsten's, range library as well as this one?  I've found
the Thorsten's hard to use because it doesn't have a dereference
function or advance function.  How can these operations be done
on ranges in that library?
