gollark: The *description* of "Gradual" is pretty understandable.
gollark: How exciting.
gollark: Its score is actually identical.
gollark: ```scheme(define actually-forgiving-grudge (lambda (x y) (let* ( (defection-count (length (filter (lambda (m) (= m 1)) x))) (lookback (+ 1 (inexact->exact (floor (expt 1.8 defection-count))))) (result (if (member '(1 0) (take lookback (zip x y))) 1 0)) ) result)))```I think this detects betrayals properly now.
gollark: Wow, BEE the memq function?
