Okay, but this kind of intuitive semantics is not what I need here. The
negation of "Maybe, I'll go to the cinema tomorrow." should be "Maybe, I
wan't go to the cinema tomorrow.". By the way, this is IMO another,
stronger argument against hardwiring multi-valued logics into a
programming language. There may be different, equally justified views on
what the natural behaviour would be.
