Wouldn't the mode be encoded in the type system via the tokens your parser is generating? I mean, every mode would be a different enum containing all the tokens that are valid in that mode?

Sure, I imagine it's possible to express any parser-generator grammar in combinator form. It's just a question of how easy it is to do by hand, and how efficient the parsing process would be.
