template<typename Rng , typename R , typename P = identity> requires input_range<Rng> && indirect_unary_predicate<R, projected<iterator_t<Rng>, P>>
constexpr iter_difference_t< iterator_t< Rng > >	ranges::count_if (Rng &&rng, R pred, P proj=P{})
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
