Beautiful work! I'm not even gonna wonder if any of it was AI-generated, because the code is clearly crafted meticulously by an experienced C engineer, very readable, and shorter than I expected.

Many thanks! It took me a long time to come up with the interface. I've been wanting a good parser combinator library for C since 2023 when I contributed to mpc[1]:
