summary
Downloads and compiles Ruby 0.99.4, uses Claude ported 0.99.4 to patch configure, prototypes and pointer/32v64 issues, finds and fixes original bugs, then runs old examples to prove 30‑year compatibility. Main claim: stop typing class for most code; give concrete rules when something is not a class — no instances, no state, abstract base, design‑pattern wrapper, data bucket, or broken constructor. Recommends extend self modules, small freestanding functions, and use structs and hashes instead of needless classes.
