maybe just:

filter(lt,[1,2,3,4]):
	def lt(x):
		return x < 2

or

filter(lt,[1,2,3,4]) where:
	def lt(x):
		return x < 2

basically something like where in haskell. but then dis doesnt save much, just reverses the order of 
the statements (and possibly removes lt from the scope after filter was called). is that really enough?
