Namespacing: The Final Frontier

When you ask the computer to notify you about external temperature but forget to specify the namespace... Congratulations, you've just discovered why variable scoping matters. The computer interprets "hot" as 1.9 million Kelvins (sun-level hot) rather than the "Earl Grey, Hot" kind of hot. Just another day where a missing prefix turns your spaceship into a thermonuclear disaster. And they say programming isn't exciting.
