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.	2012-05-03 19:45:30 -07:00
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	e09de9d6a1	classes.maybe: make maybe's slot type a classoid so you can do maybe: union{ }. Fix prettyprinting of anonymous-union/intersection. Fixes #427 , fixes #428 .	2011-11-23 01:19:09 -08:00
Doug Coleman	3e2fc2f0cb	classes: optimize instance? for classoids	2011-11-22 20:38:07 -08:00
Doug Coleman	30ade9023c	classes: add syntax for intersection{ and union{ anonymous classes. make classoid a mixin.	2011-11-22 18:49:42 -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
Doug Coleman	d3a4e72f95	classes.maybe: move maybe definition from classes.union to classes.maybe	2011-11-22 02:46:36 -08:00
