Namespaces++
PHP 6 now has namespace support checked into CVS. Unfortunately, they opted for the easy route: a single namespace construct at the top of a file declares the namespace for everything contained within that file. In other words, completely contradictory to every other construct in the language. It also limits you from ever using two namespaces within the same file. And all for no good reason. I even got involved and posted to the php.internals mailing list (unsurprisingly, with little, if any, effect).

You could always take your programming to the next level and write your own? 😉
My own language? Or my own namespace implementation for PHP?
