@deco
def fun():
    ...

is basically a syntactic sugar for

def fun():
     ...

fun = deco(fun)

In your case you would write

function = object.event(function)

As this is just an ordinary function call followed by an ordinary
assignment you can of course use different names for the decorated and
undecorated version of your function and thus keep both easily accessible.
