Indeed, it's far too early to think about forcing people to change all their code to the ? notation. I'm also not convinced of the value even once that's established; it's not like "Foo $foo = null" can ever mean *something different* from "?Foo $foo = null", it would just be an error. Maybe in 10 years' time we'll have another bonfire of unused features, and this might be one, but it's not something we can plan for right now. Regards, -- Rowan Collins [IMSoP]
