Meta-programming Memes

Congratulations, you've just built an entire programming language in 5 lines. Someone spent years architecting Python's interpreter, and you just speedran it with eval() . This is basically a REPL (Read-Eval-Print Loop) that takes user input, evaluates it as Python code, and prints the result. In an infinite loop. You know, exactly what the Python interpreter does. Except this one has the security posture of leaving your front door wide open with a sign that says "free stuff inside." The beauty here is that eval() does all the heavy lifting. Want to execute arbitrary code? Done. Want to potentially destroy your system? Also done. It's like reinventing the wheel, except the wheel is already attached to your car and you're just adding a second, more dangerous wheel. Pro tip: Never, ever use eval() on user input in production unless you enjoy surprise job openings on your team.
