    For the record you have my full support on the use of map in void context. I use if quite often and even find a certain pleasure knowing that it would not pass a certain guru [perlmonks.org]'s code reviews ;--).

      In case anyone doesn't know and cares, map in a void context is now optimized to not return any values, so it's no longer de facto inefficient.
      • I did know, but I didn't know when it was fixed. Do you know which perl fixed that?
        • My guess is 5.6.0. But I am not sure.
          • Various people in the latest TPR golf tournament, including me, had problems related to huge memory usage caused by map() in a void context. The same programs worked fine with for(). We were using 5.6.1.

            I didn't think much about it because I didn't know the optimization was supposed to have been done. Plus we all found shorter solutions later on that didn't have the memory problem.
