Minor changes (added COPYING information and other minutiae).
Delete trailing whitespace. In lambda-list-parsing.lisp this fixes a bug with ~@<newline> format directives.
Use *unify-string-case-sensitive-p* consistently. Change the documentation. templates-hierarchy.lisp: Fix stream argument to print-object.
Fixed a couple of problems with some accessors in the NUMBER, STRUCTURE-OBJECT and STANDARD-OBJECT templates.
Some modification added. Exported symbols and reverted reader macro #T to construct template instances at read time. Added MAKE-LOAD-FORM method for templates which should fix problem with SBCL. Committing in . Modified Files: substitutions.lisp templates-hierarchy.lisp unification-package.lisp variables.lisp
Fixed two problems with the unifier machinery. The first one had to do with the matching of NIL against SYMBOL and LIST in several places: essentially, the problem is incongruencies in the results of COMPUTE-APPLICABLE-METHODS in these cases. I think I caught most of them: unification of lists and the occur-check were the obvious places where things went awry. The second problem had to do with the reader macro #T. The original code generated an object at read time, which is not such a good idea. Now the code generates a call to MAKE-TEMPLATE with is evaluated later. Incidentally, the reader macro function is now called |sharp-T-reader|, in order to placate Emacs fontification. Modified Files: templates-hierarchy.lisp unifier.lisp
Fixed bugs in COLLECT-TEMPLATE-VARS for NUMBER-TEMPLATEs. If a variable was present, then the method was not returning a list. The treatment of constants like PI was also incorrect, as the numeric value was returned. Retunrning () seems the right thing to do instead.
