Message-ID <CAAHKNRGXzXcA701PREvjh4=dhYpZzg7ONo-QS7f0yKcZzCRxFw@mail.gmail.com> 
the code,

use Class::Load 0.20 'load_class';
use Moose::Role;

# VERSION

#### Attribute Definitions ####

has _log => (
    isa     => 'Log::Any::Adapter::Base | Log::Any::Adapter::Null',
    is      => 'ro',
    lazy    => 1,
    default => sub { load_class('Log::Any')->get_logger },
);


attached is the the stack trace, what about unions do I not
understand? are they only allowed between moose native types? or am I
doing something else that is obviously wrong?
