    from the perlre man page 
        \Q    quote (disable) pattern metacharacters till \E
    look at this code: 
    $comm = '(xyz';
$line = '123(xyz)456';

if ($line =~ /$comm/) {     #error! same as  $line =~ /(xyz/  which ha
+s an unmatched '('
 # do stuff
}
if ($line =~ /\Q$comm/) {   #no error! same as  $line =~ /\(xyz/  -- '
+(' is escaped
 # do stuff
}

      And I'd like to add that `perldoc perlop' says: 
      \Q          quote non-word characters till \E
      Which means 
      $a = "\Qhello! there? How> what< now%";
die $a;
__END__
hello\!\ there\?\ How\>\ what\<\ now\% at - line 2.
