> I wonder why Andy didn't chose to write the JIT in Guile itself, with a binding to Lightening, rather than in C. Guile is designed to be embedded and have bindings written for it. OP states "eventually I should be migrating this code over to Scheme anyway. And, of course, simple can mean fast, and I needed fast code generation.". That does not anwer you actual question (and neither does the article), but I gather this was to make the project finite (solve one and only one problem only at a time), not because the author was not aware.
