> It seems that it reuses the DenseUnion approach, but it would be more efficient to reuse the Struct approach. What do you think? Right, I've changed it to the struct approach. But there is room for improvement for SparseUnion: the unselect children can have any value, so we don't have to call take with the same indices for every child.
