A modern programming language that makes developers happier.

kotlinlang

On this page: <https://kotlinlang.org/docs/sealed-classes.html#sealed-classes-and-when-expression>
It says: "If it's possible to verify that the statement covers all cases, you don't need to add an `else` clause to the statement. However, this works only if you use `when` as an expression (using the result) and not as a statement".

Can you explain the last sentence in more detail? I don't see any difference in the need (or otherwise) to add an `else` clause depending on whether the `when` block is used as an expression or a statement. Is this left over from an earlier version of Kotlin?

Hi!
&gt; Is this left over from an earlier version of Kotlin?
Yes, seems like this. I’ll fix this a bit later. Thank you!
