This is handy and improves code readability, but there's one exception: if a class is using an interface, then it must be declared before being referenced. If this is a technical limitation, the error message in this case should be more descriptive than the current "Class 'MyClass' not found". The PHP 4 to 5.0.x migration guide is the only place I've found in the documentation that mentions this limitation: http://php.net/manual/pl/migration5.incompatible.php "In some cases classes must be declared before use. It only happens if some of the new features of PHP 5 (such as interfaces) are used. Otherwise the behaviour is the old." Maybe after 10 years this should be fixed?
