Problems compiling `swiftly-forward` branch.

I see tons of errors. Do I need to upgrade Xcode version or something?

Hey there, do keep discussions about that branch to the PR that references it—it's still experimental so no need to clutter the issue list with it :)

That said, currently that branch requires XCode 7 and Swift 2. I'm working on it on El Cap. It's still somewhat unstable though, and I'm working through various odd crashes here and there in some situations.

(The PR for it is #86.)

Do you prefer comments/questions on the specific pull requests?

[Shadowfiend]

Yes indeed!
