Note to readers: This document is an early draft of a model for memory-safe references that I've been working on for the last ~2 years. While I think it is quite promising, the design is unfinished. The "regions" that I present in this document have not been given a formal semantics, and I have not explained where they originate from. My goal is merely to convince you that the design is promising, and that if seen to completion, it would advance the frontier of zero-cost memory safety.

Update March 2025: I am working on a newer version of this proposal, that aims to simplify the model substantially. When I have finished that proposal, I will put a link here.

Update August 2025: Verdagon has written an awesome blog post that explains this proposal at a high level. I recommend you check it out!

Abstract

In this document, I present a novel model for memory-safe references that aims to significantly improve upon the Rust-inspired model that Mojo c

Go development environment on Windows with MSYS2

Normally, it is sufficient to grab the Go MSI installer from the website in order to set up the toolchain. However, some packages that provide Go wrappers for C libraries rely on cgo tool, which in turn, needs the GCC toolchain in order to build the glue code. Also, 3rd-party dependencies are usually hosted on services like GitHub, thus Git is also needed. This mini-guide illustrates how to setup a convenient development environment on Windows using MSYS2.

	# What this does:
	# Patches the npm-installed @anthropic-ai/claude-code cli.js to rebalance
	# system prompt instructions that cause the model to cut corners, simplify

	This is an attempt to show that Raft's safety is
	preserved with single-server membership changes as
	described in the dissertation plus the patch that a
	leader may not append a new configuration entry to
	its log until it's committed an entry from its
	current term.

	This extends the safety argument in the
	paper/dissertation. The only part that's different
	(as far as I can tell) for membership changes is Step
