franz!fizzy!jkf in Mesg 14 suggests that DESCRIBE-ARGUMENTS return a list like: (a b c &optional d e &rest r &key x y &allow-other-keys) Fahlman@c.cs.cmu.edu says that a list is hard to parse and a string should be returned instead. Is this a joke? Where are the ":-)"s? The function exists in Interlisp and is very useful.
