Description:
------------
The documentation for the dir() function, which returns an instance of the Directory class, has a list of functions and properties for that class. It lists a non-existent constructor: Directory(string $directory).

This is significant, because it incorrectly implies that it would be possible to "new up" a working instance of the Directory class by passing a path to this ctor. In fact, this will not work, because Directory has no such constructor, and the essential $handle and $path properties are created and set explicitly for each instance in the implementation of the dir() function.

The reflection code below confirms that Directory::Directory($string) does not exists, and that the $handle and $path properties are created dynamically.

Reproduce code:
---------------
<?php
ReflectionClass::export("Directory");
?>

Expected result:
----------------
N/A

Actual result:
--------------
