Send a python decorated method as a function parameter
===

I currently have the following code which uses a python library:

    f = Foo(original_method, parameters)

I would like to augment original_method, and have a decorator add a few lines of code. Let's call the new decorated method decorated_method. Finally I would like to have something like this:

    f = Foo(decorated_method(original_method), parameters)

My questions are: is this possible? how would the decorator look like? 
I must say that I can't extend original_method, since it is part of an external library.
