I was the one who asked the question
(https://tex.stackexchange.com/questions/404617). Another thing I'd
like to mention is that after a while `io.lines` simply returned nil,
and the second and third return values (error message and error code)
that io.lines is supposed to return in case of error were also nil.
Even if this issue is not perfectly fixed (i.e. even if io.lines
cannot be made to close the file descriptor when it reaches the end of
file), I think it would be preferable to throw a clear error when
there's a failure to open a new file, instead of silently (and in a
not 100% reproducible way) returning nil.
Ok, we can quit with an error but the message will be a bit different
(as we have different code). The file gets now closed explicitly which
doesn't guarantee collection but it looks ok so far. I never use
io.lines so I can't really test in practice.
