Yes I am. That's why I asked.

Given that neither your post (which I replied to) nor the post you were
replying to mentioned anything about function?() syntax, perhaps I might
be forgiven for having no idea what you were talking about?
The PEP only mentions function?() as a rejected idea, do I don't know
why we're even talking about it. The PEP is deferred, with considerable
opposition and luke-warm support, even the PEP author has said he's not
going to push for it, and we're arguing about a pedantic point related
to a part of the PEP which is rejected...
