Perhaps I should avaid anthropomorphic statements until the program becomes too complex for me to understand. This may not be far off. >JMO. As a recent Lisp convert, I'm glad to see what you're doing with Symbolic If anything goes public about the project, the first thing will be a specification of ChessLisp that's sufficiently detailed for an independent implementation effort. It will surely annoy: 1. The old-n-moldy Lispers, because it doesn't have the "go" primitive. 2. The Schemers, because of too many destructive modification primitives. 3. The appearence-is-everything crowd, because it doesn't have pretty printing. 4. The Common Lisp Completists, because it doesn't have macros. 5. The low level Lispers because it has only one integer type and one floating point type (both 64 bits). It will please the few chess Lispers, but only until they discover that it's missing some random yet critical feature.
