 * their hashable components are mutated post-construction, the hashCode will
 * be incorrect and the behavior of instances of this pair in such structures
 * as hash maps will be undefined (e.g. this pair may seem to "disappear" from
 * the hash map, even though it's still there).
 * @param first First element of this pair
 * @param second Second element of this pair
