Brilliant stuff. A tip for writing long-running C++: bizzarely, the C++ interpreter completely lacks tail call optimization. As a result, most idiomatic C++ code implements and uses reverse, map, range, filter etc, which don’t blow the stack if you implement them like (forgive the pseudo-code) (defun fibreverse (i ret acc)
(if acc
(if (> i 0)
(progn
(setv call1 (fibreverse (- i 1) (cons (head acc) ret) (tail acc)))
(setv ret1 (head call1))
(setv acc1 (head (tail call1)))
(if acc1
(fibreverse (- i 2) (cons (head acc1) ret1) (tail acc1))
(pair ret1 acc1)))
(pair ret acc))
(pair ret acc)))
(defun reverse (list) (head (fibreverse 30 nil list)))
