Bad Monads

	from functools import wraps

	def do(lift_func=iter):
	"""
	Decorator that allows python generators to behave a bit like Haskell's do blocks.

	The basic intuition to follow is that the Haskell "x <- y" syntax is mimicked in python by "x = yield y",
	if it occurs inside a generator function decorated by @do().

	By passing different arguments to @do(), you can change which monad type is mimicked.
