Calculating -------------------------------------
              caller      1.517k (± 2.8%) i/s -      7.701k in   5.082307s
      caller(1, 500)      5.438k (± 0.8%) i/s -     27.693k in   5.092926s

Comparison:
        stack_frames:    10850.6 i/s
      caller(1, 500):     5437.9 i/s - 2.00x  slower
