This assumes these will land in Swift 4.1; the attributes need to be adjusted if that turns out not to be the case. It seems @available for protocol conformances is not yet functional. I added attributes for those anyway, marked with FIXME(conformance-availability). # Conflicts: # stdlib/public/core/ExistentialCollection.swift.gyb # stdlib/public/core/Mirror.swift
