Example #1 Ds\Sequence::insert() example

<?php
$sequence 
= new \Ds\Vector();

$sequence->insert(0"e");             // [e]
$sequence->insert(1"f");             // [e, f]
$sequence->insert(2"g");             // [e, f, g]
$sequence->insert(0"a""b");        // [a, b, e, f, g]
$sequence->insert(2, ...["c""d"]);   // [a, b, c, d, e, f, g]

var_dump($sequence);
?>

object(Ds\Vector)#1 (7) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
  [3]=>
  string(1) "d"
  [4]=>
  string(1) "e"
  [5]=>
  string(1) "f"
  [6]=>
  string(1) "g"
}
