It seems inelegant to me to split this into two different modules, one to include, the other to extend.
the key thing (one of them) to understand here is that: class methods are singleton methods

Apparently when you create a subclass, that subclass's singleton class has # its superclass's singleton class as an ancestor.
This is a good thing. It allows class methods to be inherited by subclasses.

I wish to define methods within the class they belong to. Using class << self demonstrates that approach clearly — we are defining methods within the actual singleton class scope.

The distinction in computer programming between classes and objects is related, though in this context, "class" sometimes refers to a set of objects (with class-level attribute or operations) rather than a description of an object in the set, as "type" would.

Examples of different ways of defining forms
Wow, that's a lot of different ways.
The inline_form way in particular seems interesting to me, though it's worth noting that that method is just an example, not actually part of this project's code, so it's not really a first-class option like the other options.

In programming language design, a first-class citizen (also type, object, entity, or value) in a given programming language is an entity which supports all the operations generally available to other entities. These operations typically include being passed as an argument, returned from a function, modified, and assigned to a variable.
