No no, I'm not concerned about the contents of the interface. I'm wondering what, exactly, this "interface" does? I don't see how a mere interface would replace the superglobals, unless you want a superglobal request object that anyone can swap out, which sounds like a bad idea. -- Andrea Faulds http://ajf.me/
