The functionality is in cvs. I have added lexicographical_compare (also in i variant) and comparison predicates is_(i)less, is_not_(i)greater.
Check it out.
struct is_not_greater { template< typename T1, typename T2 > bool operator()( const T1& Arg1, const T2& Arg2 ) const { return Arg1>=Arg2; } };
=, isn't that is_not_less?

Shouldn't 'A' < 'a'? I'm also wondering how expensive std::toupper is. Would it make sense to do a == first to avoid the std::toupper calls in certain cases?
