  Java also has recursive patterns and (maybe still in preview) literal patterns: `switch (x) { case A(B(true, var c)) -> f(c); }`

  Java continues to try and catch up to Kotlin https://kotlinlang.org/docs/sealed-classes.html

  I didn't mind Java when the comparisons were to C++, Ruby, and Python. I can not find a reason to go back after Scala (which seemed to fail due to being indiscriminate) and especially Kotlin
