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: name.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
      module Name
        class Base
          attr_reader :location
          attr_reader :name

          def initialize(name:,
    
          def subst(s)
            if free_variables.intersect?(s.domain)
              _ = self.class.new(
                location: location,
                name: name,
                args: args.map {|a| a.subst(s) }
              )
            else
              self
            end
