 There are a number of tasks to complete, as well as a number of bugs. The purpose of this project was to dive deeper into Go, as well as get a better understanding of how programming languages work. It has been successful in those goals. There may or may not be continued work - I do plan on untangling a few messy spots, and there are a few features I'd like to see implemented. This will happen as time and interest allows.
