Groovy did so long before that ;)

  Clearly it's sad no big corporation or community is behind this beautiful language. Therefore I believe kotlin has obscoleted groovy. (except if you really want dynamic typing)

  Blows my mind how rare it is for anyone to mention groovy on hackernews. Groovy is amazing and turns java into a wild west language where anything is possible.
