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.
