I have some difficulties with recursion, and especially with the
development of the line mode construct. Below, I have reasoned in terms
of strings (the final result), comparing two potential recursive
approaches. The mark ‘𐄂’ indicates a potential issue in my process. The
arrows indicates some kind of recursion.

#+begin_src emacs-lisp
ELISP> global-mode-string
("" display-time-string)
ELISP> display-time-string
"12:00"
#+end_src

#+begin_quote
((global-mode-string ("" global-mode-string " ")))
✓ ⤷ (global-mode-string ("" global-mode-string " "))
✓  ⤷ ("" global-mode-string " ")
𐄂   ⤷ "" ("" display-time-string) " "
✓ ⤷ void
𐄂 ⤴ "" ("" display-time-string) " "
𐄂 → ("" ("" display-time-string) " ")
𐄂 ("" ("" display-time-string) " ")
𐄂  ⤷ "" "12:00" " "
𐄂  ⤷ "12:00 "
#+end_quote

#+begin_quote
((global-mode-string ("" global-mode-string " ")))
✓ ⤷ (global-mode-string ("" global-mode-string " "))
✓  ⤷ ("" global-mode-string " ")
𐄂   ⤷ "" ("" display-time-string) " "
𐄂    ⤷ "" "12:00" " "
𐄂    ⤷ "12:00 "
✓ ⤷ void
#+end_quote
