Idiomatic equals

Idiomatic equals

What’s the most idiomatic way to write


in Kotlin? Here’s what I have:

kotlin override fun equals(other: Any?): Boolean { return when { this === other -> true // unnecessary, but nice javaClass != other?.javaClass -> false other is Whatever -> == it else -> false } }

Obviously you can remove the referential equality check. But what bothers me more is still needing to include

other is Whatever

to get the flow typing to work, even thought we only reach that branch if

javaClass == other?.javaClass

, which seems to imply

other is Whatever


Anyone have something nicer?
