    Grey Fox--

    I must agree with japhy's response. I recognize the zero-width assertions, and read perlre, and I suspect that the title is a hint, too, but I just don't quite get what "(?<! always (?=" means...

    A little help, please?

    Update: Just after pressing the create button, I think I (might) have it. "Always look both ways"? (Presumably before crossing the street)?

      I wrote it with the idea of don't look at the negative behind us, but always look at the positive ahead. Grey Fox. Perl - Hours to learn lifetime to master.
      Hi roboticus;
      After looking at it again you are right, it can also be interpreted as always look both ways.
      Thanks;
