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")

Cheers.
