I know about infix operators, as well as typealias in Kotlin, but my understanding is that I wouldn’t be able to do something equivalent in Kotlin. We can’t overload or change the keywords at all. Right?

Thanks @hho. I guess that makes it safer, but I was hoping for an April Fool’s Pull Request I could put in at my office 😅

Fortunately, no you cannot do that 😮

Though you can have a lot of "fun" (pun not intended) with operators: https://github.com/angryziber/kotlin-puzzlers/tree/master/src/operators

only if you use the backtick (`) around the identifier's name

[bholota]

this yeet IllegalStateException() is closest thing to your example I can imagine

[Jacques Smuts]

literally what I ended up doing

[Jacques Smuts]

I improved it further

But why?

[Jacques Smuts]

doing stupid things to see if I can fuels my existence

[Jacques Smuts]

also it usually ends up with me learning something new.

[ribesg]

inline operator fun Throwable.not(): Nothing = throw this

fun main() {
    val error = Throwable()
    !error
}

(In the ‘weird things you can do’ category)

[Jacques Smuts]

clever

[ribesg]

inline operator fun Throwable.invoke(): Nothing = throw this

fun main() {
    IllegalStateException()()
}

[Jacques Smuts]

😬

[Ruckus]

object yeet {
   inline infix fun new(e: Exception) = throw e
}

if (tRsp.error) {
    yeet new Exception()
}

If you want to stick to the original example

[Jacques Smuts]

I have to say, putting “new” as an infix function in kotlin is the perfect abomination

[Ruckus]

😁

Wow this hurts. Remind me to never review any of your PR’s
