Why do you want to avoid having your users conform to a certain protocol? Wouldn't the users of your ORM have to conform to `DefaultConstructible` then? I'm looking at Swift ORMs, and all require users to conform to a protocol or inherit from a base class, typically named `Model` or similar.

Again, this is backwards. Rather, we know that each numerical type belongs to multiple ring algebras; there is no basis for reckoning any as "more useful." Since `init()` can only ever give us one value at a time, we know that `init()` cannot give a value that is a meaningful default with respect to any particular operation.</div><span
