-Doug Gregor [committed](https://github.com/apple/swift/commit/7519d83007443fd8092a20b700d5478a3cbeab5a) [a number](https://github.com/apple/swift/pull/5419) [of diffs](https://github.com/apple/swift/pull/5421) to improve the constraint solver by lazily creating constraints. This work prevents preallocating constraints that will be immediately simplified anyway — which should bring some decent performance improvements to the compiler.

This work prevents preallocating constraints that will be immediately simplified anyway — which should bring some decent performance improvements to the compiler.
 
 In light of the rejection of [SE-0144](https://github.com/apple/swift-evolution/blob/master/proposals/0144-allow-single-dollar-sign-as-valid-identifier.md), Robert Widmann submitted a [pull request](https://github.com/apple/swift/pull/5270) to disable the ability to use `$` as an identifier. It looks like Swift 3 point releases will continue to silently accept `$` as an identifier, but this will be an error in Swift 4.
