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: iter.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/node_with_args'

module Opal
  module Nodes
    class IterNode < NodeWithArgs
      handle :iter

      children :inline_args, :stmts

      def compile
        is_lambda! if scope.lambda_definition?

        compile_body_or_shortcut

        blockopts = {}
        blockopts["$$arity"] = arity if arity < 0
        blockopts["$$s"] = scope.self if @define_self
        blockopts["$$brk"] = @closure.throwers[:break] if @closure&.throwers&.key? :break
        blockopts["$$ret"] = @closure.throwers[:return] if @cl
    
      def compile_body
        inline_params = nil

        to_vars = identity = body_code = nil

        in_scope do
          identity = scope.identify!

          inline_params = process(inline_args)

          compile_arity_check

          in_closure(Closure::JS_FUNCTION | Closure::ITER | (@is_lambda ? Closure::LAMBDA : 0)) do
            body_code = stmt(returned_body)

            add_temp "self = #{identity}.$$s == null ? this : #{identity}.$$s" if @define_self

            to_vars = scope.to_vars

            line body_code
          end
        end

        unshift to_vars

        if await_encountered
          unshift "async function #{identity}(", inline_params, '){'
        else
