Why disallow these forms? It seems quite difficult, especially, to explain why the first one does not, or should not, work.

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.
