Ask HN: Guide for Implementing Common Lisp

Thanks. I skimmed through it a while back, so my memory might be faulty, but I think it implemented a Lisp in a Lisp. Do they actually implement this whole machinery, or do they simply use the existing mechanisms?

The later chapters talk about compilation to byte-code and IIRC how you implement that in a VM in C. But it doesn't talk about memory management and garbage collection. It has a chapter on macros.

SICP goes a little further from compiling Scheme to virtual assembly, a VM and memory management with garbage collection in their last chapter. It's all implemented in Scheme itself, including the VM, but at that point it's low-level enough that you should be able to make the step to C. It doesn't talk about macros.

Neither of which really talk about Common Lisp though and read macros etc. I'm also not sure how similar Scheme and Common Lisp compilers are.
