[swift-evolution] [Pitch] Removing Setter/Observer Name Overrides

[Will Field-Thompson]

I'm also against this (though I like the first alternative about warning on
set(oldValue) etc.).

While I think there may be value in either preventing name overrides or
requiring them here, I don't believe it's worth a breaking change. Then
again, I have never personally encountered the problem (I tend not to
override names), so maybe those who have feel differently.

I also think that if this proposal goes through I would prefer not to allow
the current name overriding syntax, even in the self-documenting case. At
that point, the self-documenting case seems like unnecessary syntactic
noise. It makes sense for a team where observer names are frequently
overridden, but when that's disallowed, I feel that the self-documenting
case adds very little.
