Mo::builder(3)	      User Contributed Perl Documentation	Mo::builder(3)

Name
       Mo::builder - Adds the builder feature to Mo's has

Synopsis
	   use Mo qw'builder';
	   has name => ( builder => 'name_lookup' );

	   sub name_lookup {
	       my ($self) = @_;
	       ...
	   }

Description
       Adds the	"builder" parameter to has, which expects a method name, which
       is executed on $self to set the attribute if it hasn't been set yet.

Laziness
       Builders	in Mo are lazy by default.  This can be	changed	by explicitly
       setting the "lazy" argument to false, in	order to cause it to be
       initialized during instantiation.

	   use Mo qw'builder';
	   has status => ( builder => '_build_status' );	     # lazy
	   has source => ( builder => '_build_source', lazy => 1);   # lazy
	   has target => ( builder => '_build_target', lazy => 0);   # eager

       To change the default behavior and make builders	to be initialized
       eagerly by default, import "nonlazy".

	   use Mo qw'builder nonlazy';
	   has status => ( builder => '_build_status' );	     # eager
	   has source => ( builder => '_build_source', lazy => 1);   # lazy
	   has target => ( builder => '_build_target', lazy => 0);   # eager
