`NonEmptyList` lacks def `updated` at index

[mcanlas]

Both NonEmptySeq and NonEmptyVector currently have this method; as does the underlying List

[LukaJCB]

I believe these were not included because it is very inefficient for NonEmptyList compared to something like NonEmptyVector. Though you could argue to include it anyway and give a warning via the scaladoc or something along those lines.

I think it is quite odd that NonEmptySeq does have updated whereas NonEmptyList does not.
Apparently, NonEmptySeq can wrap List under the hood, therefore updated may or may not be efficient depending on the underlying implementation type.

While I agree updated is not efficient, List and NonEmpty list has many O(N) operations. I think realistically we have to expect that people understand this. I'd favor consistency in this case and add the method.

Hi I’m Queen Jessa, a first-time contributor.
I’d love to take on this issue (#4763) and implement the updated method for NonEmptyList.
Could I please be assigned to this?

Hey @QueenJcloud, I don't think anyone is actively working on this so please feel free.
