Hi, Unfortunately there may be a problem with this path and namespaces in 5.3. I tried to warn about this while namespaces were being implemented, but everyone was in the "autoload will always be for classes only".
Right now when you use fully qualified name of a class when inside a namespace, you need to always prefix it with backslash: \Foo. For functions, it was deemed too hard as most internal functions remain in global space, so inside a namespace one would need to prefix every call with a backslash. If you don't prefix with backslash, the interpreter will try both options at runtime: if there's a local function, it'll run, if there isn't, it'll try to find it in global space, and only if it's not there, it'll fail. The only reason this double lookup works is because there's no autoload for functions, and it's the reasons why classes don't have this feature. There was a big discussion back about how to enable them both without severe performance penalty or unintuitive behavior, but none was found. I am myself a big proponent of autoload for functions, as there was never a good reason for excluding them from autoload (except for the artificially introduced one in 5.3).

It is used in production on hundreds of machines without any issues. Basically the patch adds the autofunc function that performs quite in the same way like autofunc, only that it does it for functions. As do you know, if PHP can not find a function it will issue a fatal error. With autofunc you can find the function somewhere and load it. Management of large no OOP projects (or mixed OOP/procedural) is much easier with this. I know that there are workarounds for loading functions, like adding them static to classes, but this is not efficient and involves important changes to code. I have attached some PHP files to test with, you must execute index.php that will load autofunc when the loaded functions can not be found. Let me know if you have any questions regarding the patch.
