- 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.
- Replace hand-written specialized-arrays.* subvocabularies with new system; instead of USE:ing specialized-arrays.T, do SPECIALIZED-ARRAY: T
- Ditto for specialized-vectors; use SPECIALIZED-VECTOR:
- io.mmap.functor: removed entirely, use <mapped-array> instead
- struct-arrays and struct-vectors have been removed because specialized arrays and vectors subsume them entirely
