The 1.4 Kotlin announcement contains multiple features. Among them there is the SAM conversion for Kotlin interfaces (previously applicable for Java interfaces only). And it's definitely a fun addition to the language. And it's really funny (try not to fun!):
fun interface Action {
fun run()
}
As much as I fun the nice and warm fun that fills me when working with Kotlin fun, I would still like to see an expansion of emotion spectrum available though. Dear Kotlin team we still need love, friendship, honesty, truth, joy, trust, care, empathy and hope. And those, when added, can become a constant reminder for a developer to become a better person meanwhile maintaining productive and professional environment. Let's make the world a better fun!
