as of yet I did not bother to implement these. if I did it would probably
jusy be in the form of macros:
(defmacro values x
    `(list ,@x))

(defmacro call-with-values (f g)
    `(apply ,f ,g))

yes, working hygenic macros were another thing I never got to...
instead I had a half-working macro system that I just used to implement
defmacro...
