Subject: Re: [PHP-DEV] Function/Constant autoloading
From: sebastian.krebs.berlin@googlemail.com (Sebastian Krebs)

Hi,

Thanks, that looks similar to what I'm looking for. It doesn't seem, 
that any of the reply is really against autoloading of functions (and 
maybe constants), but are against the given implementations (because 
they are built on top of the outdated __autoload() function), what 
brings me back to my "overall" question: Why it doesn't exists, but 
autoloading of classes exists? That makes me feel, that, since classes 
exists, functions (and the youngest children namespace constants) are 
the unloved children of the multiparadigma approach.



Just to make an example, what goes on in my mind:


// register-autoload signature
spl_autoload_register($callback, $type = SPL_AUTOLOAD_CLASS);

// register an autoloader
spl_autoload_register(function ($name, $type) use ($myLoader) {
     switch ($type) {
         case SPL_AUTOLOAD_CLASS:
             return $myLoader->loadClass($name);
             break;
         case SPL_AUTOLOAD_FUNCTION:
             return $myLoader->loadFunction($name);
             break;
         case SPL_AUTOLOAD_CONSTANT:
             return $myLoader->loadConstant($name);
             break;
     }
}, SPL_AUTOLOAD_CLASS | SPL_AUTOLOAD_FUNCTION | SPL_AUTOLOAD_CONSTANT);


class-only-autoloader can simply ignore the second argument `$type`, 
thus I don't see any BC-break.
