I found this to be a very accessible way to think about parsing a language that back-tracks naturally. I wonder how this technique would interact with an Earley parsing approach that gives all possible parses in parallel. I’m trying to imagine this with a set of rules or with dynamic runtime evaluation of what is being parsed.
