Well, not exactly what I was thinking.  I was thinking, just like the
OTHER op, that there would be only one per SELECT clause.  Allowing
multiple EitherWay ops introduces a complexity to the clause I am not
sure I like.  The EitherWay op would work the opposite of the Other
clause -- it would run if one of the When clauses evaluated to True,
where the Other clause would run if none of the When clauses evaluated
to True.

I can just imagine having to look at somebody else's Select clause,
and trace the multiple EitherWay statements to which Whens they
applied to.
