I sympathise with Klaus here. Remember that 'when' is (sort of) case
statement, and it is quite common for multiple cases to trigger the same
action. So it's either

  when (3, 4, 5) { action() }

or

  when (3) when (4) when (5) { action() }

but let's avoid having to write

  when(3) { action() }
  when(4) { action() }
  when(5) { action() }
