Help w/ a macro rules

  1. Got this working; thanks!

  2. Using () is much nicer than my solution of Nothing<T> via How do I emit a literal '::' in macro_rules?

  3. @nerditation Thank you for taking your time to write multiple iterations of the solution; This is much faster learning than The Little Book of Rust Macros

  4. @DanielKeep : Did not end up going with your code, but plagerized the return type matching / emitting from your example. Thanks!
