digitalmars.D - Sealed Containers + Ignore Interior

Now that D is starting to get serious about sealed containers, can we PLEASE, pretty please, have my patch put into the GC to allow ignoring interior pointers to data structures? (See http://d.puremagic.com/issues/show_bug.cgi?id=2927). It would be highly useful in the case where the container is sealed and the container designer therefore knows that no reference's lifetime will exceed the head reference's lifetime. Furthermore, it's safer than the alternative way of dealing with false pointers, which is to use manual memory management. If the concern is that accepting this patch would be premature optimization for the current GC, we could make it have soft semantics, i.e. fully precise GC's would not have to honor it. If the patch has succumbed to bit rot, I'd be willing to redo it, since it didn't take me very long in the first place.
