macro_rules failed in a lot of cases, this reworks it to fully support: - Complete matcher syntax. - Better bracket balancing support. - Add `lifetime` designator (1.28). - More resilient to odd syntax within the transcriber. The content doesn't have to be Rust syntax, so it can sometimes get confused. Add a few escapes so it at least doesn't barf. - At-most-once kleene operator (2018).
