If that's true, then I apologize, I was looking at the current docs, and  
Andrei's post about having some sort of "save" method.  The current docs  
definitely are not the same as what I proposed.

And in any case, my proposal requires a change to the compiler for  
foreach.  I haven't seen that talked about yet.  If that's in the works,  
then that's cool.  As I've said before, I don't need credit, I just like  
to have the ideas knocked around.
