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.

This reminds me thar there is another reason for not supplying "output ranges": out_t = boost::copy_range<out_t>( rng | xxx | yyy ); and this is optimal with RVO. -Thorsten
