If I change the last line of find_problems to call

complaining that the prob_dates argument of find_problems is unused
when I use the |= operator?
Is it complaining about that, or is it because the 'for' loop body might be
executed zero times?
The former. Almost any loop _might_ be executed zero times. Compilers and
linters etc should only complain if they can prove the loop is always executed
zero times.
