Cool. I'm also working on a Scheme compiler for embedding. Bytecode VM as well as AOT compilation to Zig. 100% written by Claude Opus under my supervision and guidance. I've given it an extensive set of tests and benchmarks (r5rs and r7rs) which helps A LOT. I currently use it embedded in a modal prose editor, mostly running integration tests for now.
I'm in the same camp. The last few months I've been building a couple of applications (editors) for my own work - and since it's so fast I've had Claude spin off to build Zig tools and libraries for markdown parsing, PDF generation, a Scheme implementation for embedding and more. (If anyone's interested they are at my Codeberg: https://codeberg.org/sicher)
