I don't think any of these seem that likely in practice, and if you do
want them, it is not hard to say:

	# Hopefully some comment here explaining the reason why you're
	# doing this.  And a more meaningful name than foo_or_bar!
	foo_or_bar = foo or bar

	@foo_or_bar
	def func(): pass

I would say leave it like this for now.  It is easy to relax the
restriction later if there's a demand.
