相互再帰した二つの型を別モジュールで定義する方法二つ
module Ex1 = struct
(* まず相互再帰した型を一モジュールで作り、その後別モジュールに分離する例 *)
module AB = struct
type a = A | AA of b
and b = B | BB of a
let a_f = function A -> B | AA b -> b
let b_f = function B -> A | BB a -> a
end

How fib is compiled in OCaml, and a hand compilation of it to Elisp
let rec fib = function | 0 -> 0 | 1 -> 1 | n -> fib (n-1) + fib (n-2)
(* Output of -dlambda *)
(setglobal Fib!
(letrec
(fib/1008
(function n/1009
(if (!= n/1009 0)
(if (!= n/1009 1)
(let
((Fib/0
(let*
((fib/1008
(lambda (n/1009)
(if (not (equal n/1009 0))
(if (not(equal n/1009 1))
(+ (funcall fib/1008 (- n/1009 1)) (funcall fib/1008 (- n/1009 2)))
1)
0))))

適当に重み付けして高得点から並べてみました。うーん。納得できるのもあるし、えってのもある。 えええ俺だけ行った事の無い、わひろ閉店?ああ、住所が違うから移転前のか。焦った。 Yong Huat は… Joo Chiat と East coast の交差点にあるきちゃないホッケンミーの店だがそんな美味いのか? Puteri Mas はドリアンパフの店。納得の高得点。 Coriander は洋風の店、つい最近出来た Geylang Lor 29 は有名なホッケンミー Katsuya はトンカツの店なんだけど…日本人としてはどうもねえ Easter & Northern Dumpling は納得。ただこないだビールをハルビンからカールスバーグに変えた。残念すぎ Joo Chiat Prawn…
