An error in a deep dive lesson "Modules: Extend and Include Part 1"? (Ruby Foundations)

Is that an error in this video (see on a screenshot)?

(the image is a little bit large, so open in a new tab in your browser)

If I dont specify attr_reader I gen an exception as follow:

``hello.rb:10:insay_hello': undefined local variable or method name' for #<Hello:0x8df827c @name="Kirill"> (NameError) from hello.rb:18:in<main>'

My ruby version:
```$ ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [i686-linux]```

Ouch. My bad, I didn't use an instance variable in my module code. How extend behaves is explained in the next video that clarifies why I made a mistake.

Resolved.
