From the profiler report, you can see that Agenda is slow on clock table
generation because I have ~org-agenda-start-with-clockreport-mode~
enabled. And this deep code invocation is from it too. It's about 5
seconds to generate the org-agenda clock table. Actually I can tolerate
this time, Just found this performance issue when profiling and curious
to ask this question.

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.
