  my $c = container PrettyBoring => as {

      # These are Bread::Board::Literal services

      service service_url => 'http://api.example.com/v0/boring';

      # And some other services depending on them...

      service dbconn => (
          class => 'DBI',
          block => sub {
              my $s = shift;
              DBI->new($s->param('connect_string');
          },

      service service_request => (
          class => 'HTTP::Request',
          block => sub {
              my $s = shift;
              HTTP::Request->new(POST => $s->param('service_url'));
          },
          dependencies => wire_names(qw( service_url ));
      };
  };

  # OR to use directly:
  my $literal = Bread::Board::Literal->new(
      name  => 'the_answer_to_life_the_universe_and_everything',
      value => 42,
  );
  $c->add_service($literal);

DESCRIPTION

A literal service is one that stores a literal scalar or reference for use in your Bread::Board.

Beware of using references in your literals as they may cause your Bread::Board to leak memory. If this is a concern, you may want to weaken your references.

See "weaken" in Scalar::Util.

ATTRIBUTES

"value"

Required attribute with read/write accessor. This is the value that "get" will return.

METHODS

"get"

Returns the "value", unaltered.

"clone_and_inherit_params"

Dies: a literal service is (essentially) a constant, it does not make sense to inherit from it.
