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?
What about that:

#include 
#include <vector>

using namespace std;
using namespace boost;

int main()
{
integer_range<int> ir=irange(7,42);
 vector<int> numbers(ir.begin(), ir.end());

return 0;
}
