Besides Kotlin, other such modern C-like languages are Java, Dart, Go, and Groovy. But because Gravity is dynamically typed, a better peer language comparison would be Javascript, Groovy, Dart, and Swift. Each of those languages was designed for a specific platform, i.e:

  * Javascript for the web in 1995

  * Apache Groovy for the JVM in 2003 (still used for Gradle build scripts)

  * Dart for the JVM and for Javascript (and more latterly for Fucshia, Android, and iOS) in 2011

  * Swift for iOS in 2014

It's good to see modern dynamically typed languages reject Python's indentation and Ruby's `end` keyword, and settle around curly braces for scoping.
