I don't think his example is great. Here is the equivalent in Django (in Python, a language that exposes 'explicit is better than implicit' as a core ideology): class Person(models.Model): company = models.ForeignKey('company', related_name='people') How is this worse than the implicit version on the post? Basing it purely on a LOC argument is flawed as implicit doesn't always mean less code, and explicit doesn't always mean more code. In this example there is actually less code, you don't need a `has_many` at all (unless it's a m2m, then it's the same LOC).
