A modern programming language that makes developers happier.

kotlinlang

we were kinda talking about this earlier in <#C0922A726|general>, but no, there isn’t really a performance difference if there isn’t any exception-throwing happening. If you’re really 110%™ certain `A` can always be cast to `B`, then the language lets you assert that unsafely. If you think there’s at all a chance you’ll run into a `ClassCastException` (_and that you can safely recover from this_), use `as?` and use tools like safe navigation and/or the elvis operator to handle it
