Hi, I got this piece of code:

val nested = listOf(listOf(12), listOf(12))
    val (one, two) = nested
    println("$one, $two")

That throws IOFB exception, I do not understand why

It works without a problem for me

same

is IOFB supposed to be

IndexOutOfBounds

exception? I’ve never seen anyone abbreviate it like that

Oh wrong code sorry

val nested = listOf(listOf(12))

replace it

I feel like you just answered your own question

@Shawn Well I kinda adopted calling exceptions in their abbreviation

If

nested

has only one element, what do you expect to happen when you destructure it into two?

Coincidentally someone asked something very relevant in #general

Related to that, can you only destructure 5 elements from a list or is it implemented differently than

componentN()

?

You can implement as many of them as you want but the stdlib happens to stop at 5.

I'll admit I've implemented the 6th one a couple of times, even though destructing really starts to look messy.
