Method/Function chaining?

Hello.

Excuse my ignorance on this, but I can't seem to find the answer I'm
looking for online... Will PHP5 be able to do "chaining" as some other
languages are able to do?

In other words...
------------------------------
<?php

class A
{
function A() { print "made an A...<br>\n"; }
function getB() { return new B(); }
}

class B
{
function B() { print "made a B...<br>\n"; }
function shout() { print "hey!!"; }
}

$a = &new A();

$a->getB()->shout();

?>
----------------------------

This kind of polymorphism is something I'm used to, and I'm hoping it
won't result in a parse error in PHP5. =)
