I like to keep up with languages.
Currently I am studying too many at once (Elixir, Scala, Haskell) so why not add another one.
This is meant to be a best of breed combination of Scala, Groovy and C#
First thought: It’s the first new language that requires explicit returns. Most recent languages that I have used simply treat the last thing in a function as the result.
I have found the Kotlin Koans project:
