Consider the computation taken from the Dictionary 3 $&.|. n where n is 1, 2, or 3 ranks and the result is the rank used by the conjunction " . In that situation &. is used and so that part is (must be?) implicit. I rather think I would also have preferred to used & to make the whole expression implicit for clearer reading: 3&$&.|. n
