If your goal is to provide a stripped down service serving a niche,
indeed. ``Professional'' use of Flex won't be able to use it then.
And the \n issue alone, agreed, does not sound terrible. There are
the others I mentioned.

I don't understand what you mean here. E.g., comments and white
spaces are not related to the parser.

As I demonstrated, what matters is to know what is to be done,
because, there is precisely not much to be done.
