So you're working in #lang racket as a naive Racket beginner, and you find some r6rs library that uses set-car!. Hey what a great idea! That enables me to do all the things I dutifully learned in a data structure course on linked lists. So I require it and it fails ... 

Yes I think we should be able to specify the list of 'good' xor 'bad' libraries, whichever is shorter.
