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 );
