Works for me

irb(main):001:0>  class X < Array
irb(main):002:1>    def to_s
irb(main):003:2>      join('.')
irb(main):004:2>    end
irb(main):005:1>    def inspect ; to_s ; end
irb(main):006:1>  end
=> nil
irb(main):007:0>  x=X.new
=>
irb(main):008:0>  x << 1
=> 1
irb(main):009:0>  x << 2
=> 1.2
irb(main):010:0>  x << 3
=> 1.2.3
irb(main):011:0> x.class
=> X
irb(main):012:0> File.join(x,'index.rb')
=> "1/2/3/index.rb"
