Yes. I think this sould be fixed into the minds of the people exacly
this way You state it:

When writing

@decorator(x,y)
def f():
    ....

not the so called "decorator" function but decorator(x,y) is the
decorating function and decorator(x,y) is nothing but a callable object
that takes f as parameter. A little correcture of Your statement: it is
NOT nessacary that a function or method will be returned from a
decorator.

def decorator(x,y):
    def inner(func):
        return x+y
    return inner

@decorator(1,2)
def f():pass

>>> f
3

This is perfectly valid allthough not very usefull ;)
