Comment:

 I am not sure about the best way to fix this. There are at least two ways
 I see:

 1. Extend circular-list? to detect circular cars
 2. Add checks for the list? and pair? cases, which would mean to either
    a) extend descseq and make the pair? case use that
    b) make a standalone check procedure and have that used also by descseq

 so basically this would work the same as the code I have proposed for
 circular lists:
 Collect all car's and check that the car's are not eq?.
