Rails' attr_readonly prevents updates from being written to the database, but does not prevent them from being changed in memory.

# Creating a whole new concern, introducing the `attr_immutable` macro
module ImmutableAttributes
class ImmutableAttributeError < StandardError; end
extend ActiveSupport::Concern
included do
class_attribute :_attr_immutable, instance_accessor: false
self._attr_immutable = []
