I tried to play with this a little more. It only prints the first line even if you remove the use warnings and run the script with perl -w or if you set the $^W. 

close(STDERR);
open(ME, "$0");
$^W=1;
while (<ME>) {
    print;
}
close ME;

It fails even if you put the $^W=1; inside the loop, but you always have to close the STDERR before opening the file.
