The comma syntax isn't supported in Python 3, so it'll be a barrier to
migration. It's also a bit less clear if you catch multiple exception
types in a single handler, which also uses a comma (to make a tuple).
Also, the 'as' syntax matches up with similar syntax for 'with' and
'import' statements.
