- MacLisp indeed does have VECTORs, STRINGs, CLASSes, etc. in an extended
- SmallTalk-like hierarchy, but they are not in the initial system. Some
- of these used to have autoload properties, but I'm not sure about the
- state of things now. None of the extended stuff got documented in the
- 1983 MacLisp manual, mostly because of Pitman's personal preferences for
- not using the extended stuff.
-
- HUNKs are relevant, because the extended heirarchy uses the USRHUNK
- feature in order to cause system functions to "trap out" on hunks,
- thereby viewing them in an object-oriented way rather than as lists
- (Glaaaag!) or as mere simple vectors.
