Re: [PERFORMANCE] Why some org code is so deep invoked?

[Bill Burdick]

You'll have this with recursive code and recursion is fairly normal in Lisp programs.

Is this deep nested code normal in Emacs Lisp?

Usually (based on my less than 20 times profiling experience), Emacs
wouldn't have deeper code than 40 levels. But my attachment profiler
report has more than 100 levels.

If this is normal and fine, It's OK. I repeat, I ask this question for
curious purpose which want to get an answer for not important question.
