Abstract:Package managers are legion. Every programming language and operating system has its own solution, each with subtly different semantics for dependency resolution. This fragmentation prevents multilingual projects from expressing precise dependencies across language ecosystems; it leaves external system and hardware dependencies implicit and unversioned; it obscures security vulnerabilities that lie in the full dependency graph. We present the \textit{Package Calculus}, a formalism for dependency resolution that unifies the core semantics of diverse package managers. Through a series of formal reductions, we show how this core is expressive enough to model the diversity that real-world package managers employ in their dependency expression languages. By using the Package Calculus as the intermediate representation of dependencies, we enable translation between distinct package managers and resolution across ecosystems.

這句話將張又俠的問題明確定義為「政治和腐敗問題」的混合體，且「政治」排在「腐敗」之前。在中共話語體系中，腐敗問題上升到「政治問題」，性質就變了。這意味著張又俠不僅僅是貪污受賄，而可能涉及到了權力鬥爭、派系活動或對中央權威的挑戰。而這兩種問題，都「危害黨的執政根基」，且張又俠又被指「嚴重助長」這兩種問題。
