Python and Johnny Cash
summary
Claims quick C‑Python hacks: AST-literals, resurrecting the print statement, lambda‑fusion. Demo builds an LD audit shim (≈10 lines of C glue) that embeds a Python resolver so the dynamic linker calls into Python, letting any program’s open/read be rewritten. Prototype makes cat and other tools git-aware open to read file contents at arbitrary commits and a zip-on-open loader; demos work live and take minutes to prototype.
