What it shows
- A tour of core built‑ins beyond the basics: printing, typing, math helpers, conversions, and utility functions commonly used in small scripts.

How to run
- From repo root with local build:
  - export FUN_LIB_DIR="./lib"
  - ./build_debug/fun examples/builtins_extended.fun
- Or, if installed: fun examples/builtins_extended.fun

Notes
- Exact behavior and outputs are documented inline at the top of the script; open the .fun file for details.
