Hmm, fair point. I was assuming that the bug in contextlib can't be
fixed with the current language behaviour (and I'd personally be OK
with the example simply adding a comment "this can't be fixed without
changing Python as proposed in the PEP"). But I'm not sure how true
that is, so maybe it's not quite as compelling as it seemed to me at
first.
