Despite the numbers saying that 'as' is almost completely unnecessary
to the proposal, I'm leaving it in for the moment, pending more data.
However, I'm removing two parts of the proposal: bare except clauses
(use "except BaseException:" if you really want that) and chaining of
excepts (use parens, "(expr except Exception1: default1) except
Exception2: default2").
