为什么值得看
Zig 核心团队实现增量编译，只重编译变更函数并直接 patch 二进制，大幅缩短 rebuild 时间。对系统语言开发者而言，这意味着 C++ 依赖的冗长编译流程有了真正替代方案。
编辑判断
C++ 的增量编译长期被头文件包含模型拖累，CMake + Ninja 的组合在大型代码库上依然动辄分钟级 rebuild。Zig 的增量编译直接 patch 二进制，跳过了传统链接阶段，这是 Rust 和 C++ 编译器都没做到的工程深度。
真正值得观察的是 Zig 把增量编译和自托管编译器结合的路径——编译器本身用 Zig 写，吃自己的 dog food，这意味着性能优化和语言特性演进可以形成闭环。如果你在做编译器或构建系统相关的基础设施，Zig 的源码和 design notes 比论文更值得关注。

核心争论：增量编译的实用边界：Zig能否扩展至优化构建与C代码，以及编译速度与安全性的权衡是否成立
Does this work for release builds or just debug builds now?
I don't think it will work with llvm/release yet but it might some day maybe. Getting incremental linker to work with llvm is kinda hard atm. Maybe the zig team has a plan dunno.
It only works with our self-hosted code generation backends (the main one being for x86_64), which right now don't have any optimisation passes. It's planned that they will in future, but that's a long-term goal. Also, any optimisations which propagate information between functions (the most obvious
