I came up with nearly the same idea after reading Guido's original post, except that I recommend using the existing dictionary literal syntax: def func (args): { author: "Guido", deprecated: True} '''doc''' pass Perhaps this was just a typo in Mike's post.

What should happen in this case?

mod_author = "Guido" author = 5

def func(self, author, mod_author): { author: mod_author}

func("Paul", "Bill")

Does the func get:

func.author = "Guido"

or

func.5 = "Guido"

or

func.Paul = "Bill"

or

...

A better solution is:

def func(self, author, mod_author){ author: mod_author }:

Although this particular example is confusing because of the reused argument names, it is still reasonably clear that the decorator is evaluated at definition time not function run time.
