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.
