Re: T operations, etc.

It seems that this operation definition syntax has been disabled in T3.1, as
shown:

** Syntax error: bad syntax for special form
  (OBJECT NIL ((ZOWIE (A B C D)) (LIST A B C D)))
>> 
> (exit)


Is there a reason that it was removed??  It sounds to me like it would be a
useful thing to have.
