[swift-evolution] [swift-evolution-announce] [Review #2] SE-0117: Default classes to be non-subclassable publicly

[John Randolph]

- infinity for this proposal.

If adopted, it will mean that whenever I want to extend a class implemented by a short-sighted developer, I’ll have to resort to wrappers and classes that own instances of the lobotomized class, etc, etc.  

java.lang.string is final.   I will never forgive Gosling for that.
