I would like to use when exhaustively when looking through some sealed classes, but there is no real result from each of the when clauses. The best I can currently do appears to be below:

val someVariableThatDoesntDoAnything = when(some) {
        is FirstClass -> {} 
        is SecondClass -> {}
    }

It seems like it would be nice to allow val _ = when(some) { ... }

We are using:

when (some) {
  is FirstClass -> {}
  us SecondClass -> {}
}.javaClass

It enforces exhaustively
