[swift-evolution] Proposal: Re-instate mandatory self for accessing instance properties and functions (David Hart)

[Kevin Ballard]

I agree, this change does not bring clarity. It just adds noise (`self.` everywhere) and removes the ability to use elided self as a reminder to watch out for retain cycles when creating escaping closures.

If you're teaching students and you're worried about mixing up local variables and properties, then feel free to always include the `self.` in your lessons. I don't see why the language has to change to enforce this one particular stylistic choice.
