Subject: [PATCH] Describe the new semantics for setting and deleting a
function's __dict__ attribute. Deleting it, or setting it to a
non-dictionary result in a TypeError. Note that getting it the first time
magically initializes it to an empty dict so that func.__dict__ will always
appear to be a dictionary (never None).
Closes SF bug #446645.
