Is there any way to obtain a this reference to a lambda from within itself?
Usecase:

val cb ={ event: SomeEventType ->
                 // Do stuff on event
                 callbackList.remove( /* How to obtain reference to self*/)
        }
        callbackList.add(cb)
        // Do stuff that will trigger cb in the list to be called

Think of a list of one-time callbacks.

No, good discussion here: https://discuss.kotlinlang.org/t/is-this-accessible-in-sams/1477/5

I haven't tried but I guess you could achieve it with a var self which is initially null. Use it inside cb and assign cb to self afterwards. Should work no? Ugly though

Works, but ugly, yes
