That's definitely worse. It causes a possibly incorrect temporary value 
to be bound, even if only for a short amount of time. The current 
behavior of only doing the store after executing the decorators is 
cleaner.

I'd rewrite the translation as:
"""
The following code:
	@f1(arg)
	@f2
	def func(): return True

  is nearly* equivalent to:
	func = f1(arg)(f2(lambda : True))

* However, you don't have the syntactical restrictions of a lambda, and 
the function name gets set to "func" instead of "<lambda>".
