Edward Loper suggested this way back on September 5, 2004.

I was and continue to be +1 on this, though I would go farther and state,
like I did at the time, that one shouldn't copy any of the function
attributes, they should come 'free', similar to the way that class
attributes are 'free' on subclasses.

What would make this _really_ nice is if one didn't need to do anything
manually; that the attribute that pointed to the decorated
function/object would be automatically applied - though I realize that
this may not be generally possible.
