Macro-expanding the following reveals that the “being the intervals” cl-loop construct fails to let-bind the loop var (i here):
(cl-loop for i being the intervals of x do (ignore))
expanding to:
(cl-block nil
(cl-block --cl-finish--
(cl--map-intervals
(lambda
(--cl-var1-- --cl-var2--)
(setq i
(cons --cl-var1-- --cl-var2--))
(ignore))
x nil nil nil))
nil)
This leads to the loop altering global variables. Emacs v28.2
