I have a question of generate. I believe one usually wants generators to have state. Yet, generator is passed by value. This is awkward, the workaround is to manually specify generate<ForwardRange, Generator&>( rng, gen ); Since Generator is the 2nd template parameter we must specify ForwardRange, which might be complicated. I wonder if we should have: template<class ForwardRange, class Generator> ForwardRange& generate( ForwardRange& rng, Generator & gen );
