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: base_schema_parser.rb
    path of file: ./repos/crystalball/lib/crystalball/rails/helpers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Crystalball
  module Rails
    module Helpers
      # Interface for schema parsers
      module BaseSche
    
        def method_missing(method_name, *args, &block)
          name = args.shift
          add_to_hash(name, options: [method_name] + args)

          new_parser = self.class.new
          add_to_hash(name, content: new_parser.instance_exec(&block)) if block
          add_to_hash(name, content: new_parser.hash)
          new_parser
        end
