   You can just pass the location up the stack alongside the type erased error. #[derive(Debug)] pub struct LocatedError { inner: Box<dyn Error + 'static>, location: &'static Location<'static>

   Any reason why you implemented your own proc macro instead of just using std::panic::Location::caller()? Right now I don't see the advantage of this crate.

   When implementing Display you only get access to an immutable reference to self, so the only possibly side effects are writes to global variables.
