Re: [boost] [Range] initial feedback on return values of algorithms

For what it's worth, the use case I most often employ is:

template<typename out_t, typename in_t>
out_t func (in_t const& in) {
  out = out_t (boost::size (in));
  do something
  return out;
}

I realize this isn't always efficient, but it's very convenient.  Also, I
hope my preferred compiler (gcc-4.1) will perform RVO.
