🌗 SBCL Fibers：輕量級協同式執行緒
➤ 以使用者層級並發解決萬級併發挑戰，兼顧高效能與程式碼清晰度。
✤ https://atgreen.github.io/repl-yell/posts/sbcl-fibers/
本文介紹了 SBCL 中正在開發的「Fibers」機制。為了克服 OS 執行緒在高併發場景下記憶體消耗巨大及排程效率低的問題，作者開發了一套使用者層級的協同式執行緒（Fibers）。Fibers 保留了傳統線性程式設計的直觀性，同時具備事件驅動模式的高擴展性。該系統特別處理了 Common Lisp 複雜的執行緒狀態（如動態變數綁定、unwind-protect 鏈及 GC 掃描），確保在切換時不會破壞 Lisp 的運行環境。這項設計以零配置、高效能為目標，旨在成為處理數萬個併發連線的理想工具。
+ 這正是 Lisp 社羣所需要的！以前要處理高併發非同步請求，非得寫出支離破碎的狀態機，現在終於能用直覺的同步程式碼風格了。
+ 實現一個與垃圾回收器無縫整合的協同執行緒系統非常困難，特別是還要處理

🌘 SBCL：一種理性可引導的 Common Lisp 實作
➤ 從 CMUCL 到獨立演進：SBCL 如何重新定義 Lisp 的構建流程
✤ https://research.gold.ac.uk/id/eprint/2336/1/sbcl.pdf
本文深入探討了「鋼鐵銀行 Common Lisp」（Steel Bank Common Lisp，簡稱 SBCL）的開發歷程及其獨特的系統引導（Bootstrap）策略。不同於傳統 Lisp 實作依賴自身或特定環境進行增量編譯，SBCL 採取了一種更為嚴謹的方法：它能透過多種不同的 Common Lisp 實作來進行構建，從而擺脫對特定主機（Host）編譯器狀態的依賴。作者透過分析 SBCL 的技術背景與演進，展示了這種開發模式如何提升軟體的可維護性，並在技術與社羣層面上對 Common Lisp 生態系統產生了深遠影響。
+ 這篇文章精確地捕捉了編譯器設計中「先有雞還是先有蛋」的經典難題，SBCL 的可攜式引導策略確實是現代化編譯器發展的
