> Keep in mind that you're not meant to invent your own dunder methods. Sometimes you'll see third-party libraries that do invent their own dunder method, but this isn't encouraged and it can be quite confusing for users who run across such methods and assume they're "real" dunder methods.
I don't think this is good advice. Example: the dunder methods implemented and used by the Scientific Python/PyData community (__array__, __array_ufunc__, __array_func__, etc.) are so, so, so important to that ecosystem.
