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: yield.rb
    path of file: ./repos/rubex/lib/rubex/ast/expression/command_call
    
    the code of the file until where you have to start completion: module Rubex
  module AST
    module Expression
      class Yield < Base
        def initialize(args)
          @args = args
        end

        def analyse_types(local_scope)
          @args = @args.ma
    
        def generate_evaluation_code(code, local_scope)
          generate_and_dispose_subexprs(code, local_scope) do
            if !@args.empty?
              code << "rb_yield_values(#{@args.size}, "
              code << (@args.map { |a| a.c_code(local_scope) }.join(',')).to_s
              code << ');'
            else
              code << 'rb_yield(Qnil);'
            end
            code.nl
          end
