Two different forms of `include` in Ruby, only one of which works as expected

class BustedInclude
include ActiveModel::Validations, ActiveModel::Validations::Callbacks
before_validation { puts 'Callback!' }
end
# outputs only `true`

Consider this. Imagine there is an online dating site that works nearly perfectly. It was coded in a garage by a couple of college dropouts. You open an account, you answer some questions, and within three days it matches you with the love of your life. It is amazing!

It is so amazing that it attracts investors. The garage becomes an office. Now the coders are surrounded by men in suits. Now the service that was once free requires a subscription; now the terms of service are quietly altered, and the data the site gathers is sold to corporations that do who knows what with it. Money changes everything!

You can’t perform that action at this time.
