The expression '(1 2 3) can also be represented by the the following more verbose notation, which matches its in-memory structure more closely: '(1 . (2 . (3 . ()))) Everything represented by '(X . Y) or produced by (cons X Y) will satisfy pair?. I hope this helps :-) Ciao, Thomas -- When C++ is your hammer, every problem looks like your thumb.
