Overview

Deprecated.

Changes to this class are discouraged as this approach is being phased out with support for those language versions.

Rails / ActiveRecord are sneaky. They define attributes of a class in one method, then monkey patch allocate in another and finally invoke module_eval in this method… but of course they use a ‘tmp’ header for the method name and then alias it in this module to name it what we expect

TODO: RUBY-714 remove w/ EOL of 2.5
