Some equivalent like autoload/Just-In-Time for non-OOP function libraries in php?

Question

I'm working on a codebase with a lot of non-OO function libraries, and personally, I don't love php's java-inspired OO model.

Unfortunately, I'm trying to solve the problem of the overhead that you get with a lot of included libraries, and see a lot of recommendation for autoloading. Which only works with classes.

Is there any way to reduce the overhead of included libraries of functions in a manner like autoload? By making use of php 5.3 namespaces, say?

I certainly don't want to move all of these (often diverse) libraries of functions to classes to get performance gain (the bugs wouldn't make it worth it), so is there a simpler way to optimize function library includes in simple ways?

Is inclusion of function libraries in php just fast enough that I shouldn't worry about it?

No, the autoloader only gets called when instantiating unloaded classes. You can't use it for functions.
