I was briefly reading GLR Parsing in Haskell and found the library based off the paper HaGLR a GLR parser combinator framework and it got me thinking. With the advent of Phoenix-2 (very nice work guys) and FC++ being worked on (to be re-reviewed for boost in the not to distant future?) there could be a possibility of direct & easy port of the haskell code to C++ using either of these libraries as it's foundation and built & used in a simillar fashion to Spirit ala expression templates (maybe an idea for Spirit 2 even). There might be an issue with Phoenix-2 (i don't know enough about the subject to know for sure) since HaGLR is based on the idea of parser combinators i'd assume it takes a simillar approach to the Parsec library using monads, from what i gather from Phoenix-2 docs there currently is no plains to support monads. So what do you guys think? :-)
