Can I match on pairs of when values? I have a status and a newState values, and I'd like to match on combinations. I could of course nest them, but I was hoping to match on a tuple like thing...

e.g.

when (status, newState) {
42, 13 -> "The answer is bad luck"
}

I think you're looking for pattern matching, which Kotlin isn't the best at, compared to some languages

[nanodeath]

you might be able to use Pair to match those, but it'd end up allocating multiple objects

[nanodeath]

e.g. when (status to newState) { Pair(42, 13) -> ... }

bummer, i was afraid of that. oh well
