* the LISP interpreter
	basically same as chapter 1

	starts to make the point about solving a number of related problems
		with a small piece of code

** rep for S-expressions
	note how this mimics def (page 26 vs. 38)
	draw picture of list '(3)

	can represent the same thing in lisp as an association list:
		'((sxptype LISTSXP)
		  (carval ((sxptype NUMSXP)
			   (intval 3)))
		  (cdrval ((sxptype NILSXP))))
	this gives some idea of what variants look like in Pascal

** rest basically same
