Research direction

Start at the implementation of mapv_into_any and compare it with mapv_into, focusing on how storage types are selected. Done means mapv_into_any preserves the source storage type, including ArcArray, and can clone it in place when no copy is necessary.

Written by the indexing model from the issue text.

Description

enhancement

Unlike mapv_into, mapv_into_any currently always returns a heap-allocated Array even if the source is something else - in my case, ArcArray.

It would be great if, like mapv_into, it was generic over storage types and allowed to clone ArcArray in-place when no copy is necessary.
