On a closer read, TFA shows strong evidence of being AI-generated, at least in parts. Overall it's just super padded and not especially insightful, and it has this quirky writing style that seems... rather familiar. But I especially want to complain about:

> Okay, maybe you want to delay creating the object until it’s actually needed — lazy initialization. Still no need for Singleton patterns.

> Use a simple function with a closure and an internal variable to store the instance:

The given example does not actually defer instantiation, which would be clear to anyone who actually tried testing the code before publishing it (for example, by providing a definition for the class being instantiated and `print`ing a message from its `__init__`) or just understands Python well enough.

But also, using closures in this way actually is an attempt to implement the pattern. It just doesn't work very well, since... well, it trivially allows client code to end up with multiple separate instances. In fact, it actually expects you to create distinct ordinary instances in order to call the "setter" (instead of supplying new "construction" arguments).

So actually it's effectively useless, and will just complicate the client code for no reason.
