In other words, calls to substr() does not trigger the resolve - a statement like "use function substr" on the other hand, does.

Ah, I see. The problem with that is, you still have to explicitly list every function you're going to use, so you might as well just use require_once, or call "load_function('substr')" directly. Well, no - there is still the issue of file names and paths becoming a dependency, besides issue of having to locate the file in the first place.

Sure, there is a small advantage over raw require statements, because you're wrapping the file-location logic in a function, which can be a bit more flexible. But that doesn't actually need the engine to do anything special: Proposed: function autoload_function($name) {

    require_once FUNCTION_ROOT . str_replace('\', PATH_SEPARATOR, $name) . '.php';

} register_function_autoloader('autoload_function'); use function Acme\Util\foo; // calls autoload_function('Acme\Util\foo'); use function Acme\Util\bar; // calls autoload_function('Acme\Util\bar'); Current PHP: function load_function($name) {

    if function_exists($name) return;
    require_once FUNCTION_ROOT . str_replace('\', PATH_SEPARATOR, $name) . '.php';

} load_function('Acme\Util\foo'); load_function('Acme\Util\bar'); All we'd really gain is a standard "name" for load_function (i.e. the "use" keyword), and I guess a built-in registry for chaining multiple callbacks together when you run it. Regards, -- Rowan Collins [IMSoP]
