中文导读
C++ 大师 Andrei Alexandrescu 在 CppCon 2015 上的高能开炮。他直指标准库 std::allocator 架构设计的缺陷，并开创性地提出通过高度可组合的小模板组件，自底向上拼装出极致高性能分配器。
为什么 HN 推它
HN 上常年热议的硬核泛型架构讲座。幽默风趣却又极具杀伤力，把组合式泛型设计和内存分配器黑魔法玩出了新高度。
「它彻底刷新了我的认知，原来写出如此精妙、优雅且兼具极致性能的堆内存分配器竟能通过这种方式实现。」HN 网友原话：It really opened my eyes to how one could very elegantly make a very complex and high-performance heap allocator
英文原摘要（HackerTube / Claude 整理）
Andrei Alexandrescu's CppCon 2015 talk argues that std::allocator is badly designed. He proposes building high-performance allocators from small composable, templated pieces.
HN repeatedly recommends it as an entertaining, mind-opening talk on allocator design and composable generic programming.
HN 上的提及
This work on composing allocators in D
I think D goes further in the Stepanov style
gave a great, entertaining, and technically elegant talk on memory allocation in C and C++ at Cppcon 2015 that is well worth watching
Andrei Alexandrescu had a great talk about allocators in C++ a couple of years ago
(mind bending stuff)
