One user's description of lvalue casts is "... there is absolutely zero
point to them ... The whole extension is just braindamaged ... I bet 99%
of the people on this list have no clue what the exact semantics of the
above are." (Linus Torvalds in
<http://seclists.org/lists/linux-kernel/2003/Dec/5431.html>). I agree.
(There may still be a case for the ObjC cases *only*, provided they can
only be written in ObjC and ObjC++ and a different ObjC-specific tree code
is used to represent them from the codes used for casts.)
