Regrettably, I've not yet seen Marpa ported from Perl. The C core `libmarpa` is only part of it. The most recent effort I've noticed is the Rust marpa and libmarpa-sys crates, but they've seemingly been inactive for a year. It might be interesting to attempt a port to language like Julia, both dynamically expressive, and with a good C ffi. Just to get a feel for the level of difficulty. Though I've a many-years-old very fuzzy recollection that the test coverage was worrisome. Even by the "shoemaker's children have no shoes" standard of our profession, the state of parsing can disappoint.
