You need the tr/// operator No, you don't need it. TIMTOWTDI, and s///g is as understandable and easy to write just like tr///. The difference in performance is impressive But typically completely irrelevant for the performance of scripts/programs of any size. This optimization feels pretty immature. When will doing 287356 of these operations per second ever be anything other than fast enough?
