       std::indirectly_comparable - std::indirectly_comparable

Synopsis

	  template< class I1, class I2,	class Comp,

	  class	Proj1 =	std::identity, class Proj2 = std::identity >
	  concept		     indirectly_comparable		     =
       (since C++20)

	  std::indirect_binary_predicate<Comp, std::projected<I1, Proj1>,
	  std::projected<I2, Proj2>>;

	  The concept indirectly_comparable specifies  the  fundamental	 algo-
       rithm requirement
	  for comparing	values across two independent ranges.

	 Semantic requirements
