Writing Hello World in 0x A Presses
summary
Claims a Rust binary can print Hello World without ever typing the letter A by using shell tricks and entrypoint hacks, and demonstrates the concrete sequence: use printf C\141 cargo new to insert an a press, avoid main by adding a custom entry point and symbol attributes, run the test harness with no capture and reopen stdout, scrub noise with ANSI escape codes, then exit early so the test runner only shows the cleaned Hello World.
