## Notes
|
||||
|
||||
- The spec interpreter is correct but slow (call/cc + dict-based ivars per send).
|
||||
- Larger Life multi-step verification, the 8-queens canonical case, and the glider-gun pattern are deferred to the JIT path.
|
||||
- Generated by `bash lib/smalltalk/conformance.sh`. Both files are committed; the runner overwrites them on each run.
