Introduce a new word-prop that makes tuple-class words classoids at parse-time so that
self-referential tuple definitions with maybe{} work, e.g. TUPLE: node { next maybe{ node } } ;
Add unit test.
Fixes#766.
- Allow methods to dispatch off union{ } and intersection{ } classes.
- Add not{ } anonymous-complement syntax.
- Define class-name for anonymous-union/intersection/complement and maybes, and clean up pprint.
- Change maybe: foo to maybe{ foo }
- Call sort-classes when making anonymous-union/anonymous-intersection classes so that they are canonicalized.
