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: logic_type_interpreter.rb
    path of file: ./repos/steep/lib/steep/type_inference
    
    the code of the file until where you have to start completion: module Steep
  module TypeInference
    class LogicTypeInterp
    
      def literal_var_type_case_select(value_node, arg_type)
        case arg_type
        when AST::Types::Union
          # @type var truthy_types: Array[AST::Types::t]
          truthy_types = []
          # @type var falsy_types: Array[AST::Types::t]
          falsy_types = []

          arg_type.types.each do |type|
            if (ts, fs = literal_var_type_case_select(value_node, type))
              truthy_types.push(*ts)
              falsy_types.push(*fs)
            else
              return
            end
          end
