Why not val/mut? Or const/mut, const/var.

  const is already a keyword - it denotes compile-time constants (basically primitive types). val is constant in runtime, but it can still be computed on the fly; just assigned only once. mut is a nice proposition, I'd certainly consider it if I were to design Kotlin

    Interesting. Why not simply overload the meaning of const based on rvalue?

      Like in C++, right? The compiler can decide whether it's a compile-time or run-time constant.

      Kotlin's "const" corresponds directly to Java's "const", so my guess is that they don't want to burn bridges with Java where there's no substantial benefit.
