That means I'll have to use let/while/setq instead of recursion
in order to "Avoid arbitrary limits", which produces less
enjoyable code.
I hoped the Lisp interpreter would use my available memory to evaluate
expressions as far as possible, until ENOMEM, instead of bothering me
with oddities like `max-lisp-eval-depth' and `max-specpdl-size'. But
for that it would need a hand-allocated stack instead of the C stack.
You probably don't want to change the implementation that much.
Emacs Lisp seems to serve its purpose as it is. It's not a functional
programming language, and it doesn't need to be one. Forget I ever asked.
