I know it's just a preview, but this just looks horribly messy and hard to understand:

I could see it being used with 3rd party classes + DI to make easy to consume internal classes. or dsls now that i think about it.

class Logger(val name: String) {
    fun log(s: String) = println("$name: $s")
}

class NotificationSender {
    fun send(s: String) = println("sent: $s")
}

context(Logger, NotificationSender)
fun store(s: String) {
    log("Stored: $s")
    send("Success")
}

@Inject
data class Storer(val logger: Logger, val ns: NotificationSender) {
    fun NotificationSender.log(s: String) = with(logger) { store(s) }
}

fun main() {
    val logger = Logger("Main")
    val ns = NotificationSender()
    
    val storer = Storer(logger, ns)
    storer.log("tacos")
}
