This looks exciting. One thing I've always wanted to do is search Rust code but excluding code in tests (marked by a #[cfg(test)] annotation). Can it do that?

  Thanks! How would you do that for a #[cfg(test)] attribute in Rust? (I believe that the true identifier of test code; `mod test {}` is just a convention). I assume Rust attributes "wrap" the AST node rooted at the node that follows them?
