Upon much inspection of the real world, and internal meditation; I find I fail at determining when a file I have open has been deleted/renamed. In attempting to use the:
  seek(ML,  0, 1); # reset end-of-file error

technique to 'tail' a file, I need a test to determine when the file has been closed (during log rotation, for example) and need to close/reopen the file name. 
require "stat.pl";
...
for(;;) {
    open ML, "</var/log/local2" || die $!;
    &Stat(ML);
    $old_ML_size = $st_size;
    #seek(ML, 0, 2); # to EOF - Not, process from beginning

    for (;;){
        &Stat(ML);
        if ($old_ML_size > $st_size) {
            print "closing the file\n";
            last;  #file closed and new one started
        }else{
            $old_ML_size = $st_size;
        }
        while (<ML>){
            another_line();
        }
        sleep 5;
        seek(ML,  0, 1); # reset end-of-file error
    }
    close(ML);
}

Repeated 'Stat' has not worked for me.
Must I depend upon someone else to signal me that the world has changed?
