BQN has four self-comparison functions, Classify (⊐), Occurrence Count (⊒), Mark Firsts (∊), and Deduplicate (⍷). Each of these is a monadic function that obtains its result by comparing each major cell of the argument (which must have rank at least 1) to the earlier major cells with match. For example, Mark Firsts indicates the cells that don't match any earlier cell, making them the first of their kind.
