Greenberg and Blatt's [Executable formal semantics for the POSIX shell](https://arxiv.org/pdf/1907.05308.pdf) should be closely read before we're done with the [`T-semantics`](https://github.com/nixpulvis/oursh/labels/T%3A%20semantics) and [`POSIX`](https://github.com/nixpulvis/oursh/milestone/1) milestone. Hopefully we'll find at least a few bugs in our code, if not whole features.
