Let E be:
pred(*i) for the overloads in namespace std;
invoke(pred, invoke(proj, *i)) for the overloads in namespace ranges.
Returns: true if E is true for some iterator i in the range [first, last), and false otherwise.
Complexity: At most last - first applications of the predicate and any projection.
