Re: [Boost-users] [range] Trying to make an "is_range" metafunction

I figured out how to do it (and it's pretty simple):

template < typename R, typename V = void > struct is_range_impl : boost::mpl::false_ {};

template < typename R > struct is_range_impl< R, boost::range_iterator< R > > : boost::mpl::true_ {};

template < typename R > struct is_range : is_range_impl< R > {};

Feel free to pick this apart; I wouldn't mind if it were made better.

Won't this always be false? In Christ, Steven Watanabe
