Interesting - it turns out we can't fully reproduce the behaviour of nested with statements in ExitStack (see the new reference test I checked in, as well as #14969)

I added one technically redundant variable to the implementation to make it more obviously correct to the reader, as well as a test that ensures the stack can handle ridiculous numbers of callbacks without failing (a key advantage of using a single frame rather than one frame per callback)

While it isn't mandatory, we prefer it if contributors submit Contributor Agreements even for small changes. If you're happy to do that, I consider emailing a scanned or digitally photographed copy of the signed form as described here to be the simplest currently available approach: http://www.python.org/psf/contrib/
