Dotty
Dotty is the next version of Scala programming language - Scala 3.0 - with a new compiler (also called Dotty)[1]. According to Martin Odersky, the creator of Dotty (and Scala in general), it will come out as a completed product in 2020.[2]
Name ‘Dotty' comes from the new foundation of the Scala language that it represents - Dependent Object Types (DOT). DOT is a core calculus for path-dependent types which enhance Scala language and its type system.[3]
The language specifications are the same in Scala 2 and Scala 3. The main difference is the compiler. Also, the type system for Scala 3 is based upon a new foundation, called the DOT calculus. Using this foundation affects which types you can use in your program, and increases confidence that if a program passes Dotty's typechecker it will not have type errors.[4]
