Well, it is not as complex as it sounds

This is the behaviour right now

- Does X exists as namespaced function (current namespace or imported)?
- Does X exists as global (builtin) function?
- Trigger error

The behaviour including autoloading would be more like

- Does X exists as namespaced function (current namespace or imported)?
- Does X exists as global (builtin) function?
- Trigger autoload
- Does X exists as namespaced function (current namespace or imported) now?
- Maybe: Does X exists as global function now?
- Trigger error

The autoloading itself could use parts already used for class-autoloading.

    // Signature
    // spl_autoload_register($callback[, $type = AUTOLOAD_CLASS]);

    $autoload = function ($name, $type = AUTOLOAD_CLASS) {
      // Do something
    };
    spl_autoload_register($autoload, AUTOLOAD_CLASS | AUTOLOAD_FUNCTION |
AUTOLOAD_CONSTANT); // "constant" here just to make it complete

Namespaced functions without autoloading seems kindof incomplete,
especially because it isn't such a big deal to simply use the prefixed one,
so the benefit seems quite small to me :X

    use MyFoo\Bar\MathFunctions as math;
    $x = math\sin($y);


Just saying :)


Regards,
Sebastian
