[swift-evolution] Playground with new Swift 4 features

[Ole Begemann]

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 playground requires Swift 4 (duh!). You need to install the latest 
Swift 4.0 snapshot from https://swift.org/download/#snapshots and, after 
installing it, select the toolchain in Xcode.

I plan to keep the playground updated over the summer as more features 
get implemented.
