Hi,

Defining a global function inside another function is not useless. Here =
is a dummy example:

```php
// a.php
spl_autoload_register(function ($classname) {
    if ($classname =3D=3D=3D 'Foo\\B')
        require 'foo/b.php';
})


// foo/b.php
namespace Foo;

class B {
    // ...
}

function some_helper(....$args) {
    // ...
}
```

The global function `Foo\some_helper` is defined inside the function =
used as autoloader.


Also, from the RFC:

> They exist in the global namespace.

I think you meant =E2=80=9CThey exist in the global scope=E2=80=9D? =
because they are defined in the namespace corresponding to the eventual =
`namespace` declaration of the file.
