'result' is the actual result. To try it out in current python:

def do_something(func):
    print("doing something")
    return func(41)**2
	
def id(x):
    return x
	
@id(lambda f: do_something(f))
def result(param):
    print("called back with", param)
    return param + 1

print("result is", result, "should be", 42**2)

-->
doing something
called back with 41
result is 1764 should be 1764

Or did I misinterpret what you were saying?
