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: compiler.rb
    path of file: ./repos/dry-types/lib/dry/types
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Dry
  module Types
    
      def visit_nominal(node)
        type, meta = node
        nominal_name = "nominal.#{Types.identifier(type)}"

        if registry.registered?(nominal_name)
          registry[nominal_name].meta(meta)
        else
          Nominal.new(type, meta: meta)
        end
