Hi all, is there any operator function to insert a list to another list at a particular index that returns the new list?

[ribesg]

There’s a version of addAll which takes an index as first parameter

[sjthn]

but it mutates the list

[sjthn]

and requires a mutable list

[ribesg]

If you want to create another list then you need to do just that

[ribesg]

Something like src.take(index) + elements + src.last(src.size - index) (this creates a useless intermediate list)

[ribesg]

But if I were you I would create a slightly longer and better optimized extension than this

[sjthn]

ya makes sense. I thought we had a extension fn for that in std lib 😛
