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>
