Nobody has *ever* caught up with Chuck Moore -- not even he himself. :) He's still tweaking Forth, even though his disciples standardized it long ago and are in a second round of standards negotiation. For Chuck's view, see http://www.intellasys.net/. Warning: here there be dragons, but not of the Dragon Book. :) 2. Lisp 1 and 1.5 were (elegant) hacks for the IBM 704 and its close descendants. As such, they're very much as elegant as the early Scheme interpreters. In one of his papers, McCarthy covers the transition from his 1960 paper to the physical implementation in another paper. I'm pretty sure it's on the web, but I don't recall where. It *should* have been reprinted in "Beautiful Code". :) -- M.
