I'm not for making peephole changes like this. It's easy to make
mistakes (even if you run the test suite) if you don't guess the type
of a variable right. I think it's better to bring code up to date in
style only as part of a serious rewrite of the module containing it --
so you can fix up all different aspects. It's often kind of strange
to see a modernization like this in code that otherwise shows it
hasn't been modified in 5 years...
(Exceptions are to get rid of deprecation warnings, or outright
failures, of course.)
