It's inappropriate to use attributes of a function for attributes that
logically belong to the decorator. For
example 'synchronized(lockattr="baz")'. The 'lockattr' logically belongs
to the synchronizing decoration. Declaring it in a separate location makes
the whole thing harder to read/understand.
