It's really two different functions packed together: if 𝕩 is a natural numberβ€”a lengthβ€”then it returns a list of numeric indices, but if it's a list of numbers, then it returns an array of list indices. This means the result always has depth one more than the argument.

The two kinds of index correspond to BQN's two selection functions: Select (⊏) works with indices along an axis, which are numbers, and Pick (βŠ‘) 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.

Now at any given position the index of the last 1, if there is any, is the maximum of all the adjusted indices so far. That's a scan ⌈`.
