Are you f'ing kidding me?!

http://www.php.net/manual/en/ref.session.php

"Some types of data can not be serialized thus stored in sessions. It
includes resource variables or objects with circular references (i.e.
objects which passes a reference to itself to another object). "

L A M E !!!

This is absurd. There shouldn't be any reason I can't send a reference to
another object -- Especially a built in type! UGH.
