Deconstructing a function like that is too invasive -- I don't want to
touch the calling sequence, for example, because it's so performance
critical.  None of the people arguing for decorators has shown a use
case for that either.  However, if you really want to do that, you
*can* take the function apart and construct a new one using the 'new'
module.
