Getting uninitialized constant Comment::Representer (NameError) in master branch
@apotonick Some offtopic at the beginning. Thanks for this framework! I can't wait to use it in production at https://inlinemanual.com. Maybe tweak the Operation bit (I am now bit influenced by Hanami::Interactor), but all the concepts are really nice. I am even thinking about rewriting our serializers from AMS to Roar, but lets see how it goes :)
Now back to the business... :beer: I am just in the middle of the book in the cells chapter and I finally got the feeling, okay lets see how it works in reality and installed this demo app. Unfortunately I got the following error:

The code from master branch is here: https://github.com/apotonick/gemgem-trbrb/blob/master/app/concepts/api/v1/thing/representer.rb#L21
I got same error in chapter-11 branches. Chapters 03-10 seems to be ok, tried almost all of them (to be explicit I test these: chapter-03, chapter-05, chapter-06, chapter-07, chapter-09, chapter-10.)
Branches master, chapter-11 and chapter-11-plural-directories gave me this error as well.
seems to be namespacing issue, when fully qualifying the representer the issue seems to be fixed :
