Can anyone give a link to the docs where this syntax is described? Can't find it here - <https://kotlinlang.org/docs/reference/typecasts.html>
I mean how "other" is smart-casted in place, not assigned to another var.

Isn't the case where if it fails will throw an Exception? So it understands that if it passes after that statement, it smart-cast it?

<https://kotlinlang.org/docs/reference/typecasts.html#unsafe-cast-operator>

Yep, I think it is. But there is an assignment in the docs. I met this one without assignment and was curious why this is not documented

I don’t think that there is an explicit site about this, but `other as MessageModel` is an expression like `other` itself. Any expression can be written top-level within a function. The value of the expression will simply be dismissed. If you were to only write `other` it would compile but IDEA would hint that the expression is pointless.
