Or any other function that has no namespace separator in front.

```
<?php

namespace Fleshgrinder\Examples;

function strlen($string) {
    return 42; // Troll! =)
}

final class SomeClass {

    public function __construct() {
        echo strlen('f');
    }

}

new SomeClass;

```

This is actually used by some in tests to provoke error conditions in
built-in PHP functions to verify their error handling.
