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

[Kevin Lundberg]

-1, for this reason, and for the extreme loss in conciseness already
mentioned elsewhere. The purported extra clarity is not worth the extra
burden placed on writing code in my opinion. I would favor a compiler
warning at the most, and this can be solved on an individual/team basis
with linting tools as well.
