On Namespaces...

[Is this the right news?] Recently I downloaded PHP 5.0.0 and read the RFCs, I sadly noticed that a Namespace proposal was declined. Why? I've been using PHP for many years and I've found problems when trying to "glue" several third parties codes. PEAR has come with a not-quite-nice solution to this problem (e.g: class HTTP_Request), and it works just fine; but I still think namespace would help a lot. I know there may be namespaces clashes, but it's far easier to replace just a line of code - i.e the namespace decl; instead of having to replace each clashing symbol all over the scripts. Manu.
