In simple terms: "fatal all" means all errors¹ warning-events die!

    At the risk of being a little pedantic LanX, your assertion isn't quite correct in this context - fatal => all actually means that all warnings (c/w errors as you claim) result in a script die'ing.

      Well I was aware of that, but since I identified only two categories of error-exceptions (signals), "dieing" and "warning", I was sure that my assertion was right. (all of them die after fatal-all)

      Now at second thought I remember all these special variables (e.g. $!, $@, $^E, $? ...) holding silent external error messages needed to be actively read and processed.

      (like in open ... or die "Terminating because $!";)

      Here you are of course right, those "errors" do not die.

      Corrected, thanks. :)
