I find this library very exciting. It is incredibly well documented, already covers a broad range of use cases, I can't wait for trying it.
There are also a lot of interesting ideas that may pollinate outside it, I love the cross-pollination capability of open source software ! (i.e. I'd love to see some of these features into parsley). Do you have a roadmap for the next releases ? Of interest to me: - restartable version ? (probably doable, if internal implementation uses immutable datastructures) - incremental version ? (Dunno if that's an easy one, and way beyond my current programming skills anyway to be able to even judge) - possibility to have transform-map(s) passed as an argument to parse, so that a collection of views can be applied in parallel and the tree be "traversed" once ? Have you tried some tests to compare performance with e.g. same grammars in Antlr ?
