Hi everyone, I'm using `when` for conditional judgment: ```when { a.isCaseA -> handleCaseA() ...

Hi everyone, I'm using when for conditional judgment:

when {
  a.isCaseA -> handleCaseA()
  a.isCaseB -> handleCaseB()
  a.isCaseC -> handleCaseC()
  else -> Unit
}

I'd like to refactor these lines with

when(a) {
  isCaseA -> handleCaseA()
  isCaseB -> handleCaseB()
  isCaseC -> handleCaseC()
  else -> Unit
}

However, it is not possible. I searched online and I know that there are a few ways to do this (assigning a val in when() , or wrapping this when() with let or with outside). I just want to use the most straightforward way.
So is it possible to directly retrieve the param of when using it or this in the future? Does Kotlin team plan to add this syntactic sugar?
Thanks. thank you color

@ephemient Thanks a lot!

If it's possible to make A, B and C the children of a sealed class/interface, then you could drop the else branch. just saying
