If you want to use (or need to use) the syntax $ARGV[0], $ARGV[1], etc. to access the arguments, you can do this:

  method => sub {
    my ($self, @ARGV) = @_;
    print "The first argument is $ARGV[0]\n";
    print "The second argument is $ARGV[1]\n";
    ...
  }

Otherwise, you can access the arguments directly from the @_ array variable:

  method => sub {
    print "I am $_[0]\n"; # print self
    print "The first argument is $_[1]\n";
    print "The second argument is $_[2]\n";
    ...
  }
