[Digir-protocol] Logical Operators

[Hobern, D. <DH...@gb...>]

I would really like to see the current suite of And, Or, AndNot and OrNot
operators replaced with And, Or and Not, all nestable in any combinations
(with Not obviously being a unary operator).  I think that that would give a
much more natural way to model many queries and would be more natural for
most programmers.  (Indeed there are some queries which I believe cannot be
modeled with the existing suite of four operators.)
