Can anyone point me to an example where a component event handler function calls a suspend fun? I'm trying:
Copy code
@Composable
fun MyButton() {
    Button(onClick = {
        launchInComposition {
            delay(10)
        }
    }) {
        Text("hello, world")
    }
}
And getting: 
@Composable invocations can only happen from the context of a @Composable function

Don't know if this is correct, but it seems to work:
Copy code
@Composable
fun MyButton() {
    val scope = remember { CoroutineScope(SupervisorJob() + Dispatchers.Main.immediate) }

    onActive { onDispose { scope.cancel() } }

    Button(onClick = {
        scope.launch {
            delay(1000)
            println("asdf")
        }
    }) {
        Text("hello, world")
    }
}
