-#        and how we're moving to y/d in this case, but when I started thinking
-#        about the ramifications of doing that, I didn't know how to rule out
-#        that opening other weird edge and corner cases so I just punted.
+#        should we do instead?  It's not at all clear to me whether z/d or
