the naming is very important. this means your packages have to have the same name as the database tables.

Actually, this is not true. When you call has_a, you just have to give it the name of an accessor in the current class that will return the primary key for the other class. You give your accessors any name you like. For example, I could change your example like this:

package MyPackage::User;
use base ('MyPackage');
MyPackage::User->table('user');
MyPackage::User->columns(Essential => qw(id role_id name lastname));

__PACKAGE__->has_a(wild_and_crazy_role => 'MyPackage::Role');

sub accessor_name {
    my ($class, $column) = @_;
    $column =~ s/role_id/wild_and_crazy_role/;
    return $column;
}
