Here's my general take on it: iterators are important and useful as the
lower-level
infrastructure. iterators are, however, not too user-friendly; the
user-friendly interface
can be build on top so easy task becomes , well, easy. and that is the purpose
of ranges and johns range library.
without a good iterator library underneith ranges where hard to craft, but now
that we have a good iterator library, we should persue
higher abstractions
