To have a hook or not to have a hook is not as important as fixing the  
bug.  If we do it first without a public hook, that is fine, then we can  
refine it later.

Let's fix the bug first, then we can worry about efficiency.  The fact  
that you can stomp on immutable memory in safeD is no good for D2.
