- Author built a Scheme compiler to WASM called Puppy Scheme as a side project.
- Development was surprisingly fast, taking most of a weekend and a few weekday nights.
- Claude AI improved compilation time from 3½ minutes to 11 seconds overnight.
- Features include 73% R5RS and R7RS support, WASI 2, WASM GC, dead-code elimination, and self-hosting.
- Includes a wasmtime wrapper for native binaries and a website running on Puppy WASM in Cloudflare Workers.
- Demonstrated a simple component model with a counter example.
- Project is alpha quality with bugs, but shows deep progress in a short time.
- Available for exploration at puppy-scheme.org, though future development is uncertain.
