Boosters,

I am considering my position on this patch. I can see that it is pleasant
syntactic sugar, but the reason I consciously omitted this was that it
suffers from combinatorial explosion. I feel that one of the nice aspects
of the current Boost.Range design is that it reduces combinatorial
explosion by breaking down items into their constituent orthogonal parts.

However I am reconsidering since there are a growing number of people
requesting this feature, and perhaps the pragmatic convenience outweighs
the slightly theoretical design concern. I need to make some effort to
tackle some of the Boost.Range suggestions that have been accumulating
during a period of ill health. I apologize for slow responses. It is
important, to me, to make interface changes that I do not later regret.
This needs some further investigation and thought.
