Hi!

Say I have a range R and I want to construct a new container from the 
range R. Will I always have to repeat the expression yielding the range, 
or is there a shorter way?

Example:

     std::vector<int> numbers(
       boost::irange(7, 42).begin(),
       boost::irange(7, 42).end()
     );

Note that it's just an example.

Is it possible to create a container C from a range expression R in one 
step? Any helper function for this?

cheers,
Martin
