Quick Return with Warning

          unless (open LOG, ">> $LOGFILE") {
            warn "Couldn't append to $LOGFILE: $!";
            return;
          }

• This is a very common locution.

• Perhaps you might prefer this:

        return warn "Couldn't append to $LOGFILE: $!"
          unless open LOG, ">> $LOGFILE";

• That returns 1 on an open failure---perhaps not what you want.

        return !warn "Couldn't append to $LOGFILE: $!"
          unless open LOG, ">> $LOGFILE";
