Consider using prepend module pattern to set constructor values in AggregateRoot about rails_event_store

[paneq]

Alternatively if we implement @loaded_events then version could be just @loaded_events.size -1 and store should append unpublished_events to @loaded_events and version getter would continue to work. But in such case we would have 2 instance variables to initialize @loaded_events and @unpublished_events so the discussion is still relevant.

  def self.included(klass)
    klass.prepend(Constructor)
  end

This is both brilliant and scary at the same time. Mutant usually gives excellent hints and enforces good code but sometimes it asks for too much. To me the lazy-loaded version is a perfectly reasonable and idomatic Ruby code
