This is quite interesting. Is `syn` just an interface to the Rust compiler's Rust parser or is it a completely separate implementation of the parser that works at compile-time? Hopefully it's not the latter but then I wonder where the slowness comes from.

it's a completely separate implementation of the parser I wish that the proc_macro API from the compiler would do that instead.

  syn also let's you define your own parsers for non-Rust syntax, way beyond what rustc could provide.
