I have read TONS of material about it*, and none of that is part of the majority of that!

In fact, the "backend" be compiler or interpreter is nearly always left as "exercise to reader".

You can't imagine how much is left to be discovered, from how make a closure, track environment, do pattern matching, memory representation, etc.

EVERYTHING interesting is something you need to look for.
