Objections have been noted and (hopefully) corrected:

I'm going for the concept of versioning data - first a single 
value, and then members of an array.  (I haven't implemented the 
versioning of arrays yet.)  That's why I said it's an inverse of 
Phobos ranges:  each iteration call to a range could give you a 
different value.  Here, several versions can point to one value.

Feedback is still most strongly welcomed.
