As I'm doing right now: tipList = tipList.dropAt(index)

If all you need is a sequence, you could do something like: inline fun <T : Any> List<T>.dropAt(index: Int): Sequence<T> = buildSequence { yield(subList(0, index)); yield(subList(index + 1, size)) } or similar with generateSequence...

Don't you need to actually yield values instead of partial lists? Unfortunately I do need an actual list, I need to "modify" an immutable list variable in-place.

[dave08]

Oops youre right, you need yieldAll, not yield...

[karelpeeters]

That exists too? I should really learn about everything coroutine-related sometime...

[dave08]

Yup, it exists... its worth it to read the docs on kotlinx.coroutines... its pretty good!

If you need it immutable because of concurrency, you could also maybe use a mutable list and check out: https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md#actors ...
