http://docs.oracle.com/javase/7/docs/api/java/lang/Object.html#hashCode() Others solve this problem in exactly this way, the Java implementation requires that you return an int. The one in that draft will allow you to return any scalar. This is much more suitable for PHP. It doesn't solve the problem directly but allows the programmer to solve it for themselves, just like Object.hashCode in Java. > > Thanks.
