Example #1 Ds\Sequence::contains() example
<?php
$sequence = new \Ds\Vector(['a', 'b', 'c', 1, 2, 3]);
var_dump($sequence->contains('a')); // true
var_dump($sequence->contains('a', 'b')); // true
var_dump($sequence->contains('c', 'd')); // false
var_dump($sequence->contains(...['c', 'b', 'a'])); // true
// Always strict
var_dump($sequence->contains(1)); // true
var_dump($sequence->contains('1')); // false
var_dump($sequece->contains(...[])); // true
?>
