Somewhat tangential - the LuaJIT source [1] is an absolute masterpiece of software engineering in C. The detailed comments (especially on the optimizations - "luajit/src/lj_opt...") are incredibly interesting reading. One of my favourite quotes is at https://github.com/LuaDist/luajit/blob/master/src/lj_opt_narrow.c#L155 https://github.com/LuaDist/luajit/blob/master/src/lj_opt_nar... ** [A recursive backpropagation algorithm with backtracking, employing ** skip-list lookup and round-robin caching, emitting stack operations ** on-the-fly for a stack-based interpreter -- and all of that in a meager ** kilobyte? Yep, compilers are a great treasure chest. Throw away your ** textbooks and read the codebase of a compiler today!] [1]: https://github.com/LuaDist/luajit https://github.com/LuaDist/luajit
