$$Loss = \frac{\text{Complexity of Output}}{\text{Compute Cost}} \times \text{Oxygen Penalty}$$

In this example, the + operator is wrapped in <oxidize> . This tells the compiler: "Evaluate this with extreme prejudice. If the stack overflows, the system does not crash; it suffocates."

Building a Telnet server in Lisp taught me something I'd forgotten:

For a Lisp REPL, this is home turf. Lisp doesn't care if you're crunching matrices, parsing XML, or listening on port 23. The code looks the same.

Telnet (and its modern descendant, the raw TCP socket) is minimalist. You open a port, you read bytes, you write bytes. That's it.
