Is

    "ABCD"[0]
								    TM
legal ANSI C?  If not, why not?  It certainly works in AT&T R&D UNIX   C.

If so then

    (#x[0])

becomes a 'charize' expression equivalent to a direct charize operator for
all intents and purposes.  I can't seriously imagine a compiler not optimizing
this expression to the character constant.
