That absolutely makes sense. For an "engine" (i.e. some sort of bytecode machine or other low-level execution model), I want compilers for both the new language as well as vanilla Elisp. Now the Elisp compiler may be a direct one, or one that works by translating into the new language first, or may actually work on top of an Elisp interpreter written in the new language. You still want to be able to migrate old source code, however, rather than just run it. -- Cheers =8-} Chipsy Friede, Völkerverständigung und überhaupt blabla
