Late defined classes

Hi all, This works (albeit with an abstract class error): --- class Result implements Countable { } $result = new Result(); --- Switching their order: --- $result = new Result(); class Result implements Countable { } --- gives : --- Fatal error: Class 'Result' not found in /tmp/not_defined.php on line 2 --- If I remove the interface, everything is peachy: --- $result = new Result(); class Result { } --- So as a user of PHP I was quite surprised that a class with an interface must be in the code flow to be defined. Is there anything (easy) that we can do to support this case? Thanks Paul
