i'm seeking single meta-function (such std::less_equal ) can used or combined in order express dominance relationship, defined follows. sequence dominates sequence b (both of having equal length) if: each element of not less corresponding element b at least 1 element of greater corresponding element of b so far best have been able come consists of 2 separate tests 1 after other follows. template<typename t> bool dominates( t& sequence1 , t& sequence2 ) { if( std::equal( sequence1.begin() , sequence1.end() , sequence2.begin() ) ) return false; return std::equal( sequence1.begin() , sequence1.end() , sequence2.begin() , std::less_equal<double>() ); } is possible same using single metafunction? the problem one-pass code have keep state - have remember whether encountered dominating element or not. writing simple for loop give advantage of short-circuiting when know result false . if want one-liner, here go: template<typenam...
