Why is this “ghetto” do_enclose line in WP files?

[mlichtenstern]

I wonder just what kind of ghetto it is referencing and who thought that was a good adjective to use? Is this an example of techie-humor?

//TODO: Tidy this ghetto code up and make the debug code optional include_once( ABSPATH . WPINC . '/class-IXR.php' );
