Well put, I've been working on an vm/interpreter design for several years. Which has to be low abstraction if it is to run fast enough to be useful. I keep painting myself into unforeseen corners, bad enough that refactoring is often not even an option. But having written code on a daily basis for 40-ish years, it's the only kind of code that tickles my brain anymore.
