 So I have promised for a long time to find some more holistic way to write down my thoughts on unsafe Rust semantics.
 I thought I could do it in 2021, but I, uh, "slightly" missed that deadline... but better late than never!

 The purpose of MiniRust is to describe the semantics of an interesting fragment of Rust in a way that is both precise and understandable to as many people as possible.
 These goals are somewhat at odds with each other -- the most precise definitions, e.g. carried out in the Coq Proof Assistant, tend to not be very accessible.

 So my compromise solution is to write down the semantics in a format that is hopefully known to everyone who could be interested: in Rust code.
 Specifically, MiniRust is specified by a *reference interpreter* that describes the step-by-step process of executing a MiniRust program, *including* checking at each step whether the program has Undefined Behavior.

 Well, yes and no. It's not *really* Rust code.
 It's what I call "pseudo Rust", uses only a tiny fragment of the language (in particular, no `unsafe`), and then extends the language with some conveniences to make things less verbose.
 The idea is that anyone who knows Rust should immediately be able to understand what this code means, but also hopefully eventually if this idea pans out we can have tooling to translate pseudo Rust into "real" languages -- in particular, real Rust and Coq.
 Translating it to real Rust means we can actually execute the reference interpreter and test it, and translating it to Coq means we can start proving theorems about it.
 But I am getting waaaay ahead of myself, these are rather long-term plans.

 So, if you want to look into my brain to see how I see Rust programs, then please go check out [MiniRust](https://github.com/RalfJung/minirust).
 The README explains the scope and goals, the general structure, and the details of pseudo Rust, as well as a comparison with some related efforts.

 If you are not used to reading interpreter source code, then I guess this can be rather jarring, and there is certainly a *lot* of work that could and should be done to make this more accessible.
 (Like, examples. I hear people like examples.)

 So for now it is serving its purpose, and maybe some of you can find it useful, too.
 Hopefully we can even use this as a starting place for seriously tackling the issue of an *official* specification of Rust.
 More on that soon. :)
