Yes, but only if it appears at the top level of a module.

I think you probably have to look at Michael Hudson's patch for semantics at
the moment.  The original PEP 318 was purely about syntax.  I made some
changes and Jim Jewett sent me some more changes which I still have sitting
in my mailbox.  I'll see if I can dig them out over the weekend and merge
them in.
