The "fat arrow" => is often also called the "fat comma", because it functions the same as the comma. So the following two pieces of code are the same, functionally:

  grep /regex/ => @_;
  
  # and

  grep /regex/, @_;

I think that perldoc perlop discusses the peculiarities of the fat arrow, but for many cases, you can simply replace the arrow by a comma.

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web
