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_.
