[swift-evolution] [swift-evolution-announce] [Review] SE-0176: Enforce Exclusive Access to Memory

[Howard Lovatt]

+1, the benefits outweigh the extra restrictions. Particularly since it is
easy to add an escaping annotation if you think the compiler is wrong.
However this will require careful documentation and good error messages so
that people know why it fails to type check and how to overcome that.
