Conventions are good, but they are very limited: enforce them too little and the programmer becomes coupled to the code—no one will ever understand what they meant once they are gone. Enforce too much and you will have hour-long debates about every space and colon (true story.) The “habitable zone” is very narrow and easy to miss.

The above works great. However, the problem comes when I want to use literal types for my legal values. In my code, I want to do that so I can make sure I define a "handler" for every legal value: const legalValues = <const>["a", "b", "c"]; // later on... // Because legalValues entries are literal types, // I get a compiler error if I forget to define any behaviors const behaviors: { [K in typeof legalValues[number]]: any } = { a: something, b: somethingElse, c: anotherThing };

We also get a hook to alter commit messages so that they include a common suffix. We can then use this to set up a server-side hook that refuses changes that don’t have this in their messages.

I've seen (and fixed) Ruby code that needed to be refactored for the client objects to use the accessor rather than the underlying mechanism, even though instance variables aren't directly visible. The underlying mechanism isn't always an instance variable - it can be delegations to or manipulations of a class you're hiding behind a facade, or a session store with a particular format, or all kinds. And it can change. 'Self-encapsulation' can help if you need to swap a technology, a library, an object specification, etc.
-
a principle I use is: If you have an accessor, use the accessor rather than the raw variable or mechanism it's hiding. The raw variable is the implementation, the accessor is the interface. Should I ignore the interface because I'm internal to the instance? I wouldn't if it was an attr_accessor.
-
But sure, go ahead and enforce self-encapsulation if you like; it makes it easier to do memoization or whatever later on.

Mutually exclusive categories can be beneficial. If categories appear several places, it's called cross-listing or polyhierarchical. The hierarchy will lose its value if cross-listing appears too often. Cross-listing often appears when working with ambiguous categories that fits more than one place.
