Bah.  I would say that it makes the whole "with" statement pointless
in case you're using "await" somewhere inside it.  In my own honest
opinion it should not be permitted to do that at all---like, it should
be a SyntaxError to use "await" inside a "with".  (This opinion is
based on a very vague understanding of async/await in the first place,
so please take it with a grain of salt.)

Just my 2 cents.
