In general, you can't get at the decorated function. Decorators can
do anything they want with the function they decorate, including
completely ignore it, or store it in a closure, assign it to a global,
add it to a data structure, etc.

Can you tell us more about the problem you are trying to solve? Why
do you want a program that access the source of decorated functions?
Maybe there's another way to get at what you need.
