This means the result always has [depth](depth.md) one more than the argument. The two kinds of index correspond to BQN's two selection functions: [Select](select.md) (`⊏`) works with indices along an axis, which are numbers, and [Pick](pick.md) (`⊑`) works with element indices, which are lists. The examples below would fail if we swapped these around. Each result from Range is a length-6 list, but their elements are different. |
