And what about SAM conversions inside effect hooks (not sure how these constructs called properly)?

@Composable
fun foo() {
    +onActive {
        (0..10).maxWith(Comparator<Int> { a, b -> a.compareTo(b) })
    }
}

this code above throws long compilation error but this code below runs fine

@Composable
fun foo() {
    +onActive {
        (0..10).maxWith(object : Comparator<Int> {
            override fun compare(a: Int, b: Int): Int {
                return a.compareTo(b)
            }
        })
    }
}

Yep, every lamba which doesn’t explicitly define the params type will break compile. They’ve been working on merging and solving this: https://twitter.com/intelligibabble/status/1153789182247985154

Sad, but at least this issue is being addressed

Really sad, trust me, I’ve been blocked by this from weeks. But since they’re already working on it I’m relieved

AFAIK, this should now be working, as of our merge that went in on Friday afternoon!

I'll give a try in some hours :)
