Its stack effect declares that ''*/'' always returns 2 values. To return a variable number of values, a word must bundle those values into a [[sequence]] (perhaps an array or vector). For example, ''factors'' (defined in ''math.primes.factors'' and demonstrated at [[Prime decomposition#Factor]]) returns a sequence of prime factors. |
