How much time ago Walter has refused this patch? Lately Walter is more receptive for your patches. I can create a new thread about this in the main D NG. If 8+ persons say they want this patch, and it works correctly, then Walter can change his mind.

Please don't do that just yet. It's something that can wait until the D2 
stuff is finished. It can be added at any time. Some of the other things 
are urgent.
