(print (eval root))
;; now. things are different.
;; HUMN is my input
;; and ROOT is "comparison of two numbers"
;; and change in root can influence results in a significant way
;; so, how'd i do that?
;;
;; what could be done then?
;; i could potentially somehow modify the operations?
;; so that (eval humn) would return
;;
;; root: pppw + sjmn
;; so. root should mean
;; pppw == sjmn
;; don't know which has HUMN yet.
;; should i then just eval those that have HUMN into a operation?
;; and others into a number?
;; well, i suppose i'd need to do pass down somehow
;; eval both parts of the root.
;; and then what?
;;
;; let's skip for now?
