Pythonで継続渡し(CPS)

1. なんでも継続からleaf-count/cps

   	def leaf_count(tree, cont):
   	if isinstance(tree, list):
   	if tree == []:
   	cont(0)
   	else:
   	leaf_count(tree[0],\
   	lambda n :\
   	leaf_count(tree[1:],\
   	lambda m : cont(m + n)))
   	else:
   	cont(1)

2. SchemeとActor理論から_fact

   	def add(x, y, k):
   	k(x + y)
   	def subtract(x, y, k):
   	k(x - y)
   	def multiply(x, y, k):
   	k(x * y)
   	def isequivalent(x, y, k):
   	k(x == y)
   	def fact(n, k):
   	isequivalent(n, 0, \
   	lambda u : \
   	k(1) \
   	if u \
   	else subtract(n, 1, \
   	lambda v :
   	fact(v, \
   	lambda w :
   	multiply(n, w, k))))
