Function object for performing comparisons. The primary template invokes operator< on const lvalues of type T with the argument order inverted. The specialization greater<void>
All specializations of greater are Semiregular.

Notes
Unlike std::greater, ranges::greater requires all six comparison operators <, <=, >, >=, == and != to be valid (via the StrictTotallyOrdered and StrictTotallyOrderedWith constraints) and is entirely defined in terms of ranges::less. However, the implementation is free to use operator>
