It might be worth you taking a > look at qscheme also, therefore. QScheme [1] has apparently been abandoned since 2000, and it looks like its VM has never been fully functional. Guile-VM seems much more mature actually. However, that of STklos is fully functional and it seems to be pretty close to Guile-VM (similar instruction set). > Hang on, I thought the instructions were byte code ... How many > levels of byte code are there, and how do they differ? Bytecode is just the binary representation of a sequence of instructions, no more. However, the compiler does use _two_ intermediate languages when compiling Scheme to VM "assembly": Scheme -> GHIL -> GLIL -> assembly (where GHIL stands for "Guile's High-level Intermediate Language" and GLIL stands for "Guile's Low-level Intermediate Language"). The former is pretty close to Scheme while the latter is closer to the VM's assembly. I think the goal was to make Guile-VM easily usable for other languages as well. Fun. ;-) Thanks, Ludovic.
