Hi, one question: What is the difference between declaring a function as a val vs declaring it as a fun on a class? I read somewhere that when calling from Java, the one defined with val becomes cumbersome to use. Is that still the case?

Property will just look as a getter from Java (with is or get prefix), but you also can rename it using JvmName

so to call it I would need to do something like obj.getFun().invoke(args) vs obj.fun(args)?

No real difference on Kotlib side, only semantics a bit different, you can check official style guide, it have some recommendations when use properties when functions

I see, I think I understand. But what is the difference between fun(args) and a returned lambda that captures the “this” keyword of the object it is a property of?

Using a val which returns a function type to use as a normal function is kind of a weird style I would say It might make sense if you use it as a value more often than immediately invoking?

So the reason I want to use it so that I can use destructuring in the arguments XD. As I understand you cannot do that in a fun?

Hmyea it's currently not possible to do destructured params I personally don't think I would use your lambda val approach though You can just do a destructured declaration on the first line of the function

I see. Well thank you for your help 🙂

if you use it as a value more often

True, but in this case client may decide and just wrap to lambda on call site or use property reference syntax
