[swift-evolution] [Review] Require self for accessing instance members

[Kenny Leung]

I know I’m responding to myself here, but a couple more points:

1. I’ve programmed in Objective-C for many years, and I don’t feel like I’ve used “self” all that often.

2. If we do enforce self, method cascading would mitigate some of the repetition.
