... still not that interesting, but at this point slightly divergent from the book: The book embraces mutability for interpreter state, initially for tracking whether an error condition has occured. I avoid this by instead defining an error type and collecting the error values, to be handled later on. Notes: So far nothing special, but this is just the beginning of the book. I like the style it is written in and it has pointed to some interesting resources, such as a 1965 paper titled "The Next 700 Languages".
