Monks, I seek your wisdom on matching an end of string/line using the qr quote like operator. I am simply trying to match a string of 8 characters, no more no less. This is not working as expected

here is my code

#!/bin/perl -w
use strict;

my $re = qr/\S{8}$/;
my $input="";
until ($input=~m/$re/) {
    $input=<STDIN>;
    chomp $input;
}

execution...

#./retest
1234
12345678
#./retest
123456789
#
