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: binary.rb
    path of file: ./repos/rubex/lib/rubex/ast/expression
    
    the code of the file until where you have to start completion: module Rubex
  module AST
    module Expression
      # Binary expression Base class.
      class Binary < Base
        include Rubex::Helpers::NodeTypeMethods
        def initialize lef
    
        def analyse_types local_scope
          @left.analyse_types local_scope
          @right.analyse_types local_scope
          if type_of(@left).object? || type_of(@right).object?
            @left = @left.to_ruby_object
            @right = @right.to_ruby_object
            @has_temp = true
          end
