Subject: Re: [PHP-DEV] Allow functions in namespaces?
From: b.muskalla@gmx.net (Benjamin Muskalla)

Hi Jessie

I think there is no need for functions in namespaces because if you want
to group functions, you can use a class.

I think the destination of the namespaces is just to group classes
together.

btw: nice patch :)
