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 === '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 “They exist in the global scope”? because they are defined in
the namespace corresponding to the eventual `namespace` declaration of the file.
