-  # Adds a new constructor that resolves the required services based on type and name.
-  #
-  # Can be included into a `class`/`struct` in order to automatically inject the required services from the container based on the type's initializer.
-  #
-  # Service lookup is based on the type restriction and name of the initializer arguments.  If there is only a single service
-  # of the required type, then that service is used.  If there are multiple services of the required type then the name of the argument's name is used.
-  # An exception is raised if a service was not able to be resolved.
-  #
-  # ## Examples
-  #
-  # ### Default Usage
-  #
-  # ```
-  # @[ADI::Register]
-  # class Store
-  #   include ADI::Service
-  #
-  #   property uuid : String = "UUID"
-  # end
-  #
-  # class MyNonService
-  #   include ADI::Injectable
-  #
-  #   getter store : Store
-  #
-  #   def initialize(@store : Store); end
-  # end
-  #
-  # MyNonService.new.store.uuid # => "UUID"
-  # ```
-  #
-  # ### Non Service Dependencies
-  #
-  # Named arguments take precedence.  This allows dependencies to be supplied explicitly without going through the resolving process; such as for testing.
-  # ```
-  # @[ADI::Register]
-  # class Store
-  #   include ADI::Service
-  #
-  #   property uuid : String = "UUID"
-  # end
-  #
-  # class MyNonService
-  #   include ADI::Injectable
-  #
-  #   getter store : Store
-  #   getter id : String
-  #
-  #   def initialize(@store : Store, @id : String); end
-  # end
-  #
-  # service = MyNonService.new(id: "FOO")
-  # service.store.uuid # => "UUID"
-  # service.id         # => "FOO"
-  # ```
