note 86049 added to control-structures.switch

Haven't seen it mentioned here, but at least in my version (PHP 5.2.5) and I'm sure all of PHP 5, the switch statement is a great way to check type safe enumerates that are otherwise missing in the PHP language. Example:

<?php

class WannabeEnum {
	/**
	 * @var WannabeEnum
	 */
	public static $FOO;
	/**
	 * @var WannabeEnum
	 */
	public static $BAR;
	/**
	 * @var WannabeEnum
	 */
	public static $FOOBAR;
	private $_ordinal;
	public function __construct($ordinal) {
		$this->_ordinal = $ordinal;
	}
}
WannabeEnum::$FOO = new WannabeEnum(1);
WannabeEnum::$BAR = new WannabeEnum(2);
WannabeEnum::$FOOBAR = new WannabeEnum(3);

function testSwitch(WannabeEnum $wannabeEnum) {
	switch($wannabeEnum) {
		case WannabeEnum::$FOO:
			echo('Foo!' . PHP_EOL);
			break;
		case WannabeEnum::$BAR:
			echo('Bar!' . PHP_EOL);
			break;
		default:
			echo('Default!' . PHP_EOL);
	}	
}
testSwitch(WannabeEnum::$FOO);
testSwitch(WannabeEnum::$FOOBAR);
?>

Outputs:

Foo!
Default!

Don't forget it uses loose comparisons!
