Why is cl-delete-if not removing items from the list? (setq
delp t) evaluates to t, so it should delete. cl-delete-if a
destructive function. This is what I'm not getting.
On my system, ‘C-h f cl-delete-if RET’ sez:
This is a destructive function; it reuses the storage of SEQ
whenever possible.
So, your question becomes: When is it NOT possible to reuse the
storage of SEQ in the process of deleting an item?
