Thanks to your book I overcame my fear of formal grammars and wrote three essential LL(1) parsers for my latest project. Where before I haphazardly ignored features like quoted strings or escaped characters, I now have extremely high confidence in my parsers’ completeness and correctness. Also the error reporting rocks and the code is easy to read! Thank you!!!

If you are at liberty to share, were these parsers for a specific domain? I'm curious about how to decide when creating a domain-specific grammar/language is worth it for any given project.

I have seen problems that probably do merit a special DSL or language, though I find it somewhat unfortunate if you need such a thing.
