De Morgan's Dream
De Morgan's Dream is a bug that haunts the dreams of every programmer. It's a logical fallacy that makes you question your own sanity.
According to legend, De Morgan's Dream is a bug that appears only in the darkest corners of the codebase, where the air is thick with the scent of despair and the coffee is always stale.
It's said that if you stare at a line of code long enough, De Morgan's Dream will appear, and you'll wonder if you've ever actually written any code at all.
But fear not, dear reader, for De Morgan's Dream is just a bug. And bugs can be caught.
