I did not follow the thread, so maybe I'm out in order, be kind with me.
After having read PEP 352, it is not crystal clear whether in:
the "except:" will mean "except BaseException:" or "except Exception:".
I would except the first, but the text beginning the section titled
"Exception Hierarchy Changes" suggests it could mean the second, without
really stating it.
Let me argue that "except BaseException:" is preferable. First, because
there is no reason to load a bare "except:" by anything but a very
simple and clean meaning, like the real base of the exception hierarchy.
Second, as a bare "except:" is not considered good practice on average,
it would be counter-productive trying to figure out ways to make it more
