I was just minding my own business, and thought to write my first 
decorator for a simple *recursive* function f. The decorator WORKS if f 
does not make a call to itself. Otherwise, f seems to have 
"difficulty" calling itself (I get a typerror, f(n) has value 
"NoneType"). What is the explanation for this? Does f have a new name 
because it has a decorator on it now?
Note: I am not using functools.wraps since I don't yet understand the 
reason I might do that yet (first things first... ).
Thanks!
