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.
