カリー化 続々

クロージャを実装できた
関数外の変数に手を出している関数をマークして
関数外の変数を一個のframeにまとめる

var a = 1
var b = 2
sub f(c: Int)
    print(a + b + c)
f(3)

↑これを↓こう変換する

var a = 1
var b = 2
sub f_(frame, c: Int)
    print(frame.a + frame.b + c)

var frame # この辺が変換部分
frame.a = a
frame.b = b
f = f_.bind(frame)

f(3)

CILに変換するときは前回の部分適用でなんとかする
今のつくりはクロージャがネストすると1関数1frameで作っているので、どんどん引数が増える
まぁいっか
