Greetings, I have the following as part of a moose package. 
  has 'ip_address' => (
     is => 'ro',
     isa => 'Str',
     lazy => 1,
     builder => 'get_ip_address',

...

  sub get_ip_address {
     my $self = shift;
     my $allclasses_file = $self->allclasses_file;
     my $ip_address;

     if ( $allclasses_file =~ m/_([^_]+$)/ ) {
        $ip_address = $1;
        return  $ip_address;
     }
  }

This works. However, if the attribute is not correct the error messege is long and unhelpful. How can I make a custom more friendly messege when the ip_address attribute is incorrect?
