We've rather taken this group, which was set up to discuss Tom Stuart's Understanding Computation book, off topic with all the talk of the Little Schemer book club.
Please join and or post this new group if you want to hear about the Little Schemer book club or continue discussions about what to do next.
Of course if you want to continue discussing Understanding Computation (and directly related topics) then keep posting to the "Understanding Computation discussion" group.
