A modern programming language that makes developers happier.

kotlinlang

I've spent some time today trying to figure out what was happening here. Finally got it. It turns out that `object`s behave a bit different that I thought they were. After deserializing an `object`,  a totally new instance is created. This produces `NoWhenBranchMatchedException` when comparing with and old instance of `object`. See provided code for an example.
Maybe IDE should warn developer that using when branch without `is` might be dangerous?
