Interesting. But I wonder: apart from backwards compatibility,
wouldn't it make more sense to reimplement the basic routines
of the typesetter in the chosen language instead of tacking
an interpreter onto the typesetting engine to expose internals
that were never designed to be accessed externally?

And I doubt the string-based stack is any more "real" than
the "constructed-variable" version. It only appears pretty
because the implementation is short, which hides the inherent
inefficiency of repeatedly having to rescan the string to
divide it into separate elements and then to glue them all
together again. (My design stems from an experiment to see
how far I could come using only 2-character names, thus the
idea of storing everything inside a single string.)
