My problem with this syntax is that it can be hard to read:
return if self.arg is None then default else self.arg looks worryingly like return NAME NAME.NAME NAME NAME NAME NAME NAME NAME.NAME to me.
I think that requriing parens helps a lot with the list-of-names problem
it nicely delimits the conditional expression for human readers:
return (if self.arg is None then default else self.arg)
In particular it breaks up the misleading grouping "return if".
