I meant the rest of the information specifically about funs.

Nobody, least of all me, was suggesting a special tag for
empty tuples, merely that they could fit into one of the
immediate classes.  It does mean that if you want to
represent the equivalent of Haskell's (Maybe [t]), that
is an optional list, where an empty list not the same as
no list, then {} | list(T) is not a good choice; it is
better to use an atom, e.g., undefined | list(T).  It will
take less memory, be quicker to match, and clearer to read.
