Rok Mihevc commented on ARROW-17141:
------------------------------------
Oh, that's neater than I remember.
Would it make sense to add a field path utility here to enable alternative way
of selecting? E.g.: field_path_to_indices("parent_field.child_field") ->
\{parent_field_idx, child_field_idx}. It would be purely for syntactic sugar.
> [C++] Enable selecting nested fields in StructArray with field path

> Currently selecting a nested field in a StructArray requires multiple selects
> or flattening of schema. It would be more user friendly to provide a field
> path e.g.: field_in_top_struct.field_in_substruct.
