Syn 0.15 is out and makes it possible for a procedural macro to produce parse errors that are as good as you would get from the current macro_rules based library! macro. Procedural macros are being stabilized in Rust 1.30 in a few weeks. Let's re-implement library! to make it more flexible and maintainable.
