Just checking - in a when block like this:

import java.time.Period

fun Period.toDays() = when (this) {
  Period.ofYears(1) -> 365
  Period.ofMonths(1) -> 30
  else -> days
}

the check is an equality check, not an identity check, isn't it?

I'm getting a compiler warning Identity-sensitive operation on an instance of value type 'Period' may cause unexpected behavior or errors., but surely this is an equality check...

(Ignore the obvious issues with assuming the length of years and months...)
