Don't needlessly intern symbols, #'function-arglist, #'cl-function-arglist 2009-09-20 Aidan Kehoe <kehoea@parhasard.net> * help.el (function-arglist): Show the double-quotes in the sample output, correctly. Bind print-gensym to nil, now we're using uninterned symbols. Don't #'mapcar + #'intern to create uppercase symbols, use #'loop and #'make-symbol instead. * cl-macs.el (cl-upcase-arg): Don't intern the upcased symbols we're using for cosmetic reasons. Trust #'true-list-p in #'cl-function-arglist to detect circularity. (cl-function-arglist): Bind print-gensym to nil, now we're printing uninterned symbols and would prefer to avoid the gensym syntax. (cl-transform-lambda): Only add the Common Lisp lambda list: argument information when that differs frmo the normal argument information.
