I wonder if Kotlin's persistent collections have these missing APIs.

Yes they do, and the operation is called just `removeAt`: https://github.com/Kotlin/kotlinx.collections.immutable/blob/07bccd5d647792e0954c5ae59b5fbdf2c6dc626b/kotlinx-collections-immutable/src/main/kotlin/kotlinx/collections/immutable/ImmutableList.kt#L26

Cool. I'll try to switch and see if anything breaks.

Sadly I've found some real basic stuff missing.

take(Int), drop(Int)...

Interesting project tho.

I'm not sure I'd extend Kotlin's List interface. It gives false sense of having everything there, like map, associate, etc.

For immutable collections I'd expect them to return immutable types.

I have to say it was smart from your side to use pcollections as implementation behind and first work on the API.
