   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?
I do something like this:

template <class SinglePassRange>
boost::container::vector makeVector(const
SinglePassRange& rng)
{
  boost::container::vector v(boost::begin(rng),
boost::end(rng));

  return move(v);
}

and using it surprisingly often as move semantics allow for cheap
return-by-value

I guess you would also add template parameter for container type.
