A decorator is an immediately evaluted function. It is evaluated at
declaration time, not at instance creation time. If it does some magic
tricks like passing the decorated method to an external library, it
does the magic on the exact method that it prepends. Also:
is equal to:
bar = foo(bar)
So you really overload the decorator's output, not the original method.
