 In PHP 4, it was necessary to use a reference to create a callback that
 points to the actual object, and not a copy of it. This is no longer the
 case.

 Also, I found more instances of {{{$var = &my_func();}}}. I have not
 touched any instance of {{{$var1 =&$var2;}}}. All unit tests pass (minus
 {{{Tests_Theme_WPTheme::test_wp_theme_uris_with_spaces}}} which always
 fails).
