Anti-pattern Memes

The emperor has no clothes, and the singleton has no excuse! Someone finally said what we've all been thinking but were too polite to admit in code reviews. You can dress up your global variable in a fancy getInstance() method, add some lazy initialization, throw in some thread-safety concerns, and call it a "design pattern" all you want—but at the end of the day, you're still accessing the same single instance from anywhere in your codebase like it's 1995. It's literally just global state with extra steps and a superiority complex. The Singleton pattern strutted into town acting all sophisticated with its private constructor and controlled access point, but really it's just your good old global variable wearing a tuxedo to the function. Both will haunt your testing suite and make dependency injection cry in the corner.
