Anyone have any idea why this isn’t working? (

val people = setOf(personA, personC)

)

json {
        "test1" to array(personA, personC) //works
        "test2" to array(*people) // does not work
    }

interface KlaxonJson {
fun array(vararg args: Any?) : JsonArray<Any?> = JsonArray(args.map { convert(it) })
// ...

The spread operator

*

only works on arrays, not sets.

Yeah. So you'd need to

.toTypedArray()

first.

You'd need that instead.

I meant that you need to call

.toTypedArray()

before you use the spread operator, but you'd end up with

(*people.toTypedArray())

and I think the precedence works out so that the set is converted to an array before the spread operator is applied. (Sorry for using "first" in a horribly ambiguous way.)

Yeah I mean that if you want to convert a set to an array you don't need

*

and

toTypedArray

, just the latter will do 😒imple_smile:

makes me wonder if it would be a good idea to make the spread operator overloadable

yikes, the thought on adding

operator fun spread

is 3 years old. probably not gonna happen at this point
