Actually, I made some other changes:
use Data::Dumper::Concise; # For Dumper().
And:
sub My_Actions::do_attribute
{
my($hash, $t1, $t2, $t3) = @_;
=pod
print "do_attribute()\n";
print '$t1: ', Dumper($t1);
print '$t2: ', Dumper($t2);
print '$t3: ', Dumper($t3);
=cut
return [$t1, $t2, $t3];
}
sub My_Actions::do_basic {
my ($hash, $t1, $t2, $t3, $t4 ) = @_;
=pod
print "do_basic()\n";
print '$t1: ', Dumper($t1);
print '$t2: ', Dumper($t2);
print '$t3: ', Dumper($t3);
print '$t4: ', Dumper($t4);
=cut
return [$t1, $t2, $t3, $t4];
}
The output is:
