Looking forward to this. There's very different approaches taken by production grade VM's today, ie the difference between JVM, MRI and CPython. Will there be any introspection into the theory vs implementations in production today. I've found books like "Ruby under a Microscope" to be invaluable when driving into a completely new runtime. Was hoping this would be a good spot to collect many VM approaches.
