This project was created because the old nbt package has had a 1-liner open issue preventing compilation for 2 years now at the time of writing, despite submitting a pull request to fix it. While I was at it, I went ahead and changed the data structure to use konsumlamm's rrb-vector package instead of lists or unboxed arrays for more well-rounded asymptotics. StrictData is also turned on, and some functions are exported for reading/writing NBT files that remove some of the old boilerplate code.
