Safe Made Easy Pt.1: Single Ownership is (Not) Optional
Summary
This post proposes a practical approach to memory safety using linear typing and flow-sensitive, refinement-based type systems. It compares with C++ and Rust, explains the idea of widening ownership to Option<T> and refining with Some<T>, and outlines the theoretical foundations of abstract interpretation and dependent typing. The piece previews an upcoming multi-part series on implementing these ideas in a new language.
