2. the work in that bobkonf talk for @spritelyinst is continuing apace; i think we are maybe 90% done for core Guile, e.g. call-with-prompt is working though abort-to-prompt isn't yet. still quite some prelude / stdlib work to do, and compiling multiple modules in a single compilation unit; maybe 2 calendar months out. Follow along at https://gitlab.com/spritely/guile-hoot if that is your thing.
3. more ephemerally, i have a little bare-bones baseline-style compile-to-c scheme in the works. uses the c control stack but a side value stack, so as to have packed GC roots. the compiler is in scheme of course. the intent is to be a useful-enough approximation of a production system to use when testing https://github.com/wingo/whippet-gc/. who knows if it is fit for purpose though; will publish when it works 🤪
