Doug Coleman ce91d0cc1d classes: Add a check that arguments to classoids are themselves classoids.
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.

Doug Coleman cb42258144 classes:
- 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.

Doug Coleman d7aee3256e classes.maybe: Change the type of maybe's class slot. As a result, maybe: maybe: integer is valid now, so fix the unit tests and its prettyprinting. 2011-11-23 01:43:02 -08:00
Doug Coleman 627bce6615 classes: Make methods dispatch on maybes. Fix a couple bugs in the implementation of maybe. classoid? is now a dumb test if an object could be a well-formed classoid; valid-classoid? tests for well-formedness. Move maybe tests. Make pprint* work better on methods. 2011-11-22 15:12:20 -08:00
