More yucky than wrapping the Py3 version in an
exec? To my way of thinking, that cancels out any
elegance that might have been gained from using
a with-statement.

Do you really need to use the context manager
at all? Could you just write the try-statement
that you would have written in Py2 if you
didn't have a context manager?
