Any ideas what this means?

Because your on function is not inline, that lambda is considered as a closure, and because closure is self-contained, it must "capture" stuff in the outer scope, and now that it's not possible to directly modify a local variable in a closure, that local is wrapped into an object with a var member for the closure to "modify".

oh ok

How can i fix this issue

[Loney Chou]

either inline your on function or rather just ignore it

[Yusuf.I]

The thing is it is already inlined

[Yusuf.I]

inline fun <reified T : Event> EvenTester.on(
    crossinline consumer: suspend Event.(T) -> Unit
): EventListener {
    return object : EventListener {
            override suspend fun onEvent(event: Event) {
                if (event is T) {
                    event.consumer(event)
                }
            }
        }
        .also { this.addEvent(it) }
}

Sorry for the delay. Because consumer is crossinline, anything inside it should be captured to be used in this EventListener object, so consumer is effectively closure. You need to ignore that "Captured..." info then. To be honest this is not a big deal.
