If not, you'll probably get people (newbies at least) trying to write stuff like this:
def foo(a): if a > 5: @attr: "bob" elif a > 0: @attr: "skip" else: @attr: "guido" The other forms (via a decorator, using explicit attribute assignments after the definition) make it explicit that these attribute assignments don't occur in the context of function execution.
Hmmm... What about
def foo(a): attributes: author = "Guido" deprecated = 1 body: b = sqrt(a) return 3 * b / 2
Would that provide sufficient clues that the attributes are not part of the body?
