Limit the scope of the changed value of $/, by "local"izing it, and enclosing it in the smallest block possible: 
{ # Add an enclosing block
   local $/= "\n\n\n";
   while(<>){
      local $/="\n"; # Reset to normal behaviour inside loop only
      my ($filename)=/^(\S+)/;
      my $text=reader::firstline($filename);
   }
} # End enclosing block.

This code avoids "Action at a distance", by making wierd settings in as limited a scope as possible.

        This is not an optical illusion, it just looks like one.
