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: top.rb
    path of file: ./repos/opal/lib/opal/nodes
    
    the code of the file until where you have to start completion: # frozen_string_li
    
      def compile
        compiler.top_scope = self
        compiler.dynamic_cache_result = true if sexp.meta[:dynamic_cache_result]

        push version_comment

        helper :return_val if compiler.eof_content

        if body == s(:nil)
          # A shortpath for empty (stub?) modules.
          if compiler.requirable? || compiler.esm? || compiler.eval?
            unshift 'Opal.return_val(Opal.nil); '
            definition
          else
            unshift 'Opal.nil; '
          end
