PHP or: how I learned to stop worrying and define functions with reserved names

gistfile1.php

<?php

class Magic {
  function _list() {     return "list"; }
  function _function() { return "function"; }
  function _and() {      return "and"; }

  function __call($name, $args) { return $this->{"_$name"}(); }
}

$m = new Magic;
var_dump($m->list());
var_dump($m->function());
var_dump($m->and());
