I'm not really excited about that; CAST is more verbose and not
particularly more readable (at least IMO).  What I was wondering about
was altering the internal representation to remember which format had
been used, and reverse-listing in that same format.  That would both fix
this issue, and please users who have a stylistic preference for one or
the other format.
