I believe that dereferencing a type cast is a bad idea.  This is just
like case variant records, but messier.  You should only need to do
this type of stuff in a very few places and having to do something 
grungy (like untagged variant records) will flag the few places with
a blazing mark to all who read the code.  If you make it too easy to
type cast and do other illicit deeds, I think programmers will take
advantage far too often.  Here is a random example from C:

    in_lnaof(((struct sockaddr_in *)&ifinet->if_addr)->sin_addr)

Yes, this is actual code that took me about 3 minutes to find 
in the 4.2 UNIX kernel.  I happen to know where the real bad
parts are.....
