This example demonstrates how Ruby overrides object equality to ensure that distinct instances with the same `id` are treated as identical, using ActiveSupport’s `present?` and the `alias :eql? :==` pattern. It shows the result of `Array#uniq_by` (from Active Support) collapsing three `Article` objects into one, even though they are separate instances. The code relies on `attr_accessor :id`, the `==` method, and the `eql?` alias to define value-based comparison. The output is a single `Article` object, illustrating the effect of custom equality in collections. The implementation uses Ruby’s core classes and Active Support extensions.
