How does @inlinable relate to the @_specialize attribute described in https://github.com/apple/swift/pull/6797 (original swift-evolution post about it: https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20160314/001449.html)? Here's how I understand it: @_specialize emits the specialized

[swift-evolution] Playground with new Swift 4 features

Hello, if you'd like to try out some of the new features coming in Swift 4, I made a playground to do just that. I thought I'd tell the list about it because some of you may find it useful. You can download the playground on GitHub: https://github.com/ole/whats-new-in-swift-4 The playgroun

[swift-evolution] NSString.contains(_:) returns false for empty string argument

Six weeks ago there was a discussion [1] (and a subsequent fix [2]) about the behavior of `String.hasPrefix(_:)` and `String.hasSuffix(_:)` with empty string arguments. After the fix, `str.hasPrefix("")` always returns `true`. This leads to inconsistent behavior with the `NSString.contains(_:)`
