That's the sort of restriction I imagined that Guido was tending towards. While it's justifiable in this context, I would prefer to leave the option of using arguments available, in case someone comes up with a use where function attributes are inappropriate. 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.

Not to mention the fact that you'll have to start prefixing your function attributes so that you don't clash between decorators.. because of the flat namespace.
