Parser combinators are fine for languages not designed to be written by people, but the error messages tend to be awful. What's increasingly clear to me, having designed a few languages, is that a well designed languages is easy to parse. I work on a couple of languages which require one token lookahead. This means when something goes wrong, we know exactly where the problem is, and what token we didn't expect.
