Dragging this back to some semblance of reality: Whenever you write
code, you're writing code for some kind of executor. No level of
abstraction higher or lower truly matters; you just write to the level
you're aiming at, and everything else is of educational curiosity
only. I might write code for a Python executor one day, and for a C
executor another, and then another day maybe I'm writing LaTeX code -
that's a language, too, of a sort. If I build my own framework layer
above the base executor, that's just added another type of executor to
the pool, and now I can target that. Everything's abstractions around
something, and *it doesn't matter*, because anyone can fiddle with any
layer without disturbing the others. Those eight-state cells can be
dropped in without breaking my Python code - that's the whole point of
abstractions. They're doing their job.
