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: singleton_class.rb
    path of file: ./repos/opal/lib/opal/nodes
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'opal/nodes/scope'

module Opal
  module Nodes
    class SingletonClassNode < ScopeNode
      handle :
    
      def compile
        push '(function(self, $parent_nesting) {'

        in_scope do
          body_stmt = stmt(compiler.returns(body))

          add_temp '$nesting = [self].concat($parent_nesting)' if @define_nesting
          add_temp '$$ = Opal.$r($nesting)' if @define_relative_access

          line scope.to_vars
          line body_stmt
        end

        line '})(Opal.get_singleton_class(', recv(object), "), #{scope.nesting})"
      end
