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: literal.rb
    path of file: ./repos/steep/lib/steep/ast/types
    
    the code of the file until where you have to start completion: module Steep
  module AST
    module Types
      class Literal
        attr_reader :location
        attr_reader :value

        def initialize(value:, location: nil)
          @location = location
          @value = value
        end

        def ==(
    
        def back_type
          klass = case value
                  when Integer
                    Builtin::Integer
                  when String
                    Builtin::String
                  when Symbol
                    Builtin::Symbol
                  when true
                    Builtin::TrueClass
                  when false
                    Builtin::FalseClass
                  else
                    raise "Unexpected literal type: #{(_ = value).inspect}"
                  end
