A recursive descent parser is exactly what I made for a programming language I am making
It was an interesting exercise, especially when I needed to add error recovery and proper error message generation

I had a prof once who spoke the king's, so when he said "Parser" it sounded like "Pauser". I could understand it, but it confused the heck out of my Hungarian classmate.
