it fixes the issue The method keyword returns an instance of the MooseX::Method::Signatures::Meta::Method class, which is a subclass of Moose::Meta::Method, which is a subclass of Class::MOP::Method.
Moose allows a method object for default, but not for trigger, which must be a regular coderef.
code :
trigger => method { $self->clearer }->body,
trigger => sub { shift->clearer },
Why does this DI code declare a method-scope var and then assign it to a static, class-level object?

This might help you If the container is assigned to the static property at once, then the static property would reference a container that is not yet fully initialized, which could have unwanted consequences.
Assigning the container to the static property only when it is fully initialized prevents others from using a partially initialized container.

like below fixes the issue The scope of the class containing the producer really shouldn't matter a whole lot, however, the scope of the item being produced matters. If there isn't a scope annotation on the producer field / method then it will produce that object at the scope of the containing class.

Does that help The specification treats producer methods as beans (basically, producer is a definiton of how you create an instance of given bean type). Therefore a rule applies, that if no scope is provided, @Default is assumed.
Hence the answer to your question is - the producer scope is @Default if none is specified. There is no link between producer scope and the scope of the bean on which it is declared.
code :
@ApplicationScoped
public MyBean {

  @Produces //this will produce @Dependent
  public Foo produceDependent() {
    return new Foo();
  }

  @Produces
  @RequestScoped //produces the scope you define
  public Bar produceReqScopedBean() {
    return new Bar();
  }
}

This might help you I try to create attributes within a class using a method. It is possible to create an attribute, but how can I add a scope to the attributes? For example i want wachtwoord(password) to be private, but firstname to be public. , You'll need to declare the properties in advance:
code :
class UserEntity extends Entity {

    private $wachtwoord;
    public $firstname;

    ...
}
