One thing that I'm not entirely sure how to implement
using ranges alone is regex_search. The basic problem
is that in order to implement match_results, we need
to create a sub-range delimited by two iterators
*both of which are derived from the begin iterator*
Ranges effectively make the begin and end iterators
completely disjoint.
