I have a couple of questions. First, regarding that syntax. This means (if I understand CDBI correctly) that I need to use my classes as so: 
my $parent1 = Person->create({ name => 'P1' });
my $parent2 = Person->create({ name => 'P2' });

my $child = Person->create({ name => 'C1' });

# This seems like a cumbersome way to set up the relationships
$child->add_to_parents({ parent => $parent1 });
$child->add_to_parents({ parent => $parent2 });

# Or, alternatively
# $parent1->add_to_children({ child => $child });
# $parent2->add_to_children({ child => $child });

Is there any way to sucessfully set those relationships when I'm constructing the objects?

Also, I thought of adding a single parent_id column to the person table, but wouldn't that prevent a given person from having multiple parents?
