Allocation de solidarité unifiée ( #ASU ) https://mastodon.social/@la_voix/116306904851255157 : #Macron ne restera pas seulement dans les mémoires comme le président des riches. Il sera aussi celui qui s’en est pris aux pauvres. Après la baisse des aides personnelles au logement ( #APL ), la réduction des indemnités chômage et le conditionnement du #RSA, son 1er ministre, #Lecornu, s’apprête à présenter un texte qui risque de se transformer en nouvelle arme contre les plus précaires. https://www.msn.com/fr-fr/politique/gouvernement/allocation-de-solidarit%C3%A9-unifi%C3%A9e-comment-le-gouvernement-fusionne-les-prestations-sociales-pour-mieux-les-attaquer/ar-AA201bWP

🌘 TinyAPL 組合子（Combinators）索引與技術參考
➤ 符號的詩學：TinyAPL 組合子與原語參考指南
✤ https://tinyapl.rubenverg.com/docs/info/combinators
本文為 TinyAPL 語言的技術說明文檔，詳細梳理了該語言中的函數、算子及組合子體系。TinyAPL 繼承了 APL 家族簡潔的符號表達特性，並引入了受《To Mock a Mockingbird》啟發的組合子命名法（如 Bird、Kestrel、Warbler 等）。文件核心在於定義「組合子」——即僅引用參數與運算元而不進行任何狀態修改的純函數。透過對這些原語與組合子的系統化分類與索引，TinyAPL 提供了一套極具函數式美感的算子架構，協助開發者利用這些符號進行高階的邏輯抽象與運算。
+ 這份文檔結構非常清晰，對於想要深入 APL 函數式風格的開發者來說，將組合子以鳥類命名（Bird-style naming）不僅有趣，也方便記憶複雜的函數嵌套。
+ 驚訝於 TinyAPL 如何將如此龐大的運算集合濃縮在

Combinators - TinyAPL

A combinator is a function or operator that only refers to its arguments and operands without modifying them in any way.
