Hello there 👋 , I have a question regarding closures/lambdas in Kotlin. How come variables accessed from a closure in Kotlin don’t need to be final as oppose to Java where they need to be effectively final?

I found this, but I’m still curious about the implementation details. 🤔 Any pointers? 🙇

The non final vars are said to be captured by the lambda. The compiler generates a wrapper around the non finals and exposed those in the lambda

👍 Awesome, thank you for clarifying this!
I wanted to see the actual generated code. Sharing the results in case someone else would be interested:).
