You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: dispatch.rb
    path of file: ./repos/puppet/lib/puppet/pops/functions
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Puppet::Pops
module Functions
# Defines a connection between a implementation method and the signature that
# the method will handle.
#
# This interface should not be used directly. Instead dispatches should be
# constructed using the DSL defined in {Puppet::Functions}.
#
# @api private
class Dispatch < Evaluator::CallableSignature
  # @api public
  attr_reader :type
  # TODO: refactor to parameter_names since that makes it API
  attr_reader :param_names
