What Python could do with reasonable ease is a sort of "promise" model, where 
an I/O operation returns an object that waits for the I/O to complete upon 
access or destruction.

Something like

def foo():
	obj = stdin.delayed_read()
	obj2 = stdout.delayed_write("data")
	do_lengthy_computation()
	data = obj.get()	# Here we wait for the read to complete
	del obj2		# Here we wait for the write to complete.

This gives a fairly nice programming model.
