Subject: Re: Redefining CAR/CDR/other standard symbols (was Re: [Q] Dylan to Java/JVM compiler?)

You cannot redefine common-lisp:car and common-lisp:cdr as functions, but you may certainly define a foobar:car and foobar:cdr and shadow-import them into a package that otherwise uses the common-lisp package. The section you quote from is concerned with symbols in the common-lisp package, not symbols with the same name as those in the common-lisp package. This confuses a lot of people from one-namespace, no-packages languages. If you really want a different make-instance, perform the same trick. #:Erik -- Travel is a meat thing.
