And There Was Much Rejoicing
Brother Maynard closes the Book of Arrays. The counting has been mastered — zero through (- length 1), no more, no less. The Holy Hand Grenade has been lobbed: (nums:map (fn (:number x) (* x 2))). The array is transformed without counting, without mutation, without off-by-one errors.
“And there was much rejoicing.”
“Yay.”
The Knights return. “We demand… a CLASS!” Chapter 20 beckons. The Knights are never satisfied for long.
