Really, I don't think this example is all that bad even without the parens:

sum(x[3] except IndexError: 0 for x in list_of_tuples)

Compare:

sum(x[3] if len(x)>3 else 0 for x in list_of_tuples)

which is a roughly-comparable LBLY check doing the same thing, and
which doesn't need parens. If you want 'em, go ahead, put 'em in, but
it's not horrible without them.
