As I mentioned at python-ideas I believe that parens neutralize,
at least to some extent, that unfortunate statement-ish flavor
of the colon.
This one has some statement-like smell:
msg = seq[i] except IndexError: "nothing"
But this looks better, I believe:
msg = (seq[i] except IndexError: "nothing")
Or even (still being my favorite):
msg = seq[i] except (IndexError: "nothing")
