Example

import std.algorithm: sort;

// As a type
assert(sortingPredicate!(typeof([1].sort!"a < b"))(1, 2) == true);
assert(sortingPredicate!(typeof([1].sort!((a, b) => a > b)))(1, 2) == false);

// As a value
assert(sortingPredicate!([1].sort!"a > b")(1, 2) == false);
assert(sortingPredicate!([1].sort!((a, b) => a < b))(1, 2) == true);

// Default predicate
assert(sortingPredicate!(int[])(1, 2) == true);
