$USERDEFINED problem. In Lisp there are car, cdr and often(?) cddr
cadr,... which access members of lists (cadr acesses the second
element, cddr the third, fourth .... element). Absolutely no need to
put this into ruby itself though. Its more a mnemonic and shorter to
type. Example (setq mylist '((1 a))) then (car (cdr 'mylist)) is the
same as  (caar 'mylist) which is 1.
