 	Some other Scheme details:
 
 	*	`#t` is true and `#f` is false
 	*	`(lambda () ...)` constructs a thunk
+	*	there is no difference in meaning between `[...]` and `(...)`; we just sometimes use the square brackets for clarity
 	*	`'(1 . 2)` and `(cons 1 2)` are pairs (the same pair)
 	*	`(list)` and `'()` both evaluate to the empty list
 	*	`(null? lst)` tests whether `lst` is the empty list
