Hello all 👋 I don't want to spark a big discussion, and hopefully this is the right channel but I was wondering what the state of expression trees in Kotlin is. I see some messages stating that it's planned but I don't seen anything other than that. Anyone here has any idea?

What is an expression tree?

This is what I'm referring too: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/expression-trees/

What are those expression trees good for?

seems pretty much like a tool to create DSLs and Kotlin already has extensive capabilities in that area

It's not for DSLs or anything. In C# you would use it to convert lambda statements into SQL queries (or any other query language for that matter)

Andrey Breslav mentioned expression trees in Kotlin on one of conference, but as I know there is no proposal or ETA

Thanks for info! Too bad there is no official statement
