 * Rationale / TODO
 
+The ultimate goal of this patch set is to have arrays be strictly layered 
above typed vectors so they can be replaced by a different implementation 
without affecting the latter.
+
 ** Status as of 3.0.0
   
   - The _elements functions require the array handle interface even for true 
vectors, when all of handle, inc and off are unnecessary. This creates a burden 
(having to declare & release handles, etc).
