# Multiple inheritance with Modules as an alternative to injected composition
# from Sandi Metz's talk [Nothing is Something](http://confreaks.tv/videos/bathruby2015-nothing-is-something)
# Like Sandi's 'direct' DI method this has behavior outside of the base class
# that gets composed together. However in this gist I compose modules in class
# definitions instead of injecting collaborators.
# Tradeoffs between this and Sandi's version are that in this case the API consumer doesn't
# have to know how to make a RandomEchoHouse (no `house = House.new(formatter: Whatever.new)`),
# but also the API consumer can't make anything not already accounted for either.
