Yes getHoles returns an array of holes. At least I had hoped. Here's a shortened version of the board.pm where getHoles is defined. 
package board;
...

use lib('.');
use hole;

#
# new - board constructor
#
# holes ) is an ref to a array of hole objects
#         This is not typically passed in to the
#         constructor.  The constructor will build
#         the holes attribute $holes is not passed.
#
# level ) is also not typically used.
#
sub new {
    my ($pkg, $holes, $level) = @_;

    unless ( $holes ) {
        #
        # create the holes
        #
                ...
    }
    my $obj = bless {
        holes    => $holes, # ref to array of holes
        level    => defined( $level ) ? $level : 0
    }, $pkg;
    return $obj;
}

sub getHoles {
    my $obj = shift;
    return wantarray ? @{$obj->{'holes'}} : $obj->{'holes'};
...
1;
}
