;; well, this seems like this could be done with (eval)
|
|
;; would it be possible for me to also translate
|
|
;; xxx + yyy into (call xxx) + (call yyy)
|
|
;; that would be neat

;; so. have mashmap from symbol name into operation
|
|
;; and have (my-eval)?
|
|
;; it will take symbol name, and either return number directly from the map
|
|
;; or will wrap the names into my-eval and run operation on them?
|
|
|
|
;; is there a way to have less code and reuse existing lisp things?
|
|
;; if there's direct number, i could just run (defparameter lfqf 4)
|
|
;; and then execute root directly, i think
|
|
;; or what, i'd need to also define all the intermediate symbols,
|
|
;; (setq a (+ c d)) ; complains that C is unbound
|
|
;; how could this be a lazy eval?
|
|
;; well. hm
|
|
