I am distracted by the need to write: (defun truthy (x) (not (not x))) or if you's is the kind of organization that builds a development v.s. a production version... (defmacro truthy (x) #+dev `(not (not ,x)) #-dev `,x) It would be nice to have a code base that is more truthy. _______________________________________________ pro mailing list pro@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/pro
