Apologies if this was announced elsewhere: is commit access to master restricted?
I noticed I couldn't merge some documentation improvements in https://github.com/apple/swift/pull/3815, and just wanted to make sure this was due to Swift 3 finalization. If commit access is restricted, is it safe to assume that restriction will be lifted on or around July 29? - Brian Gesiak On Thu, Jul 28, 2016 at 7:15 AM, Anton Zhilin via swift-evolution < [email protected]> wrote: > > https://github.com/apple/swift/commit/c8c41b385c0312e562abe4952fa2d6794dec2e0f > Is SE-0077 going to be implemented for Swift 3? > > > https://github.com/apple/swift/blob/master/stdlib/internal/SwiftExperimental/SwiftExperimental.swift > Does this code actually run? > > If so, I will add "implemented" to the proposal, plus I still haven't > added latest naming changes. ¯\_(ツ)_/¯ > > 2016-07-28 1:17 GMT+03:00 Tony Allevato via swift-evolution < > [email protected]>: > >> I noticed that while SE-0091 appears to be implemented (from a cursory >> glance at some of the affected types like Equatable and String), it looks >> like the named methods are still part of the FloatingPoint protocol and >> they still use global operators. >> >> Is anyone tracking the migration of that protocol (and possibly also the >> new Integer protocols) to use the new operator technique?
