在cppnow 2023的演讲中，daisy展示了简化模板元算法的技巧。她以排序为例，通过将type_list中的每个Type映射到它们的index，然后对index数组进行排序，最终重新安放type_list中的元素。她展示了一个巧妙的排序算法，使用variant数组和std::visit访问数组中的元素。通过使用std::type_identity作为仿函数参数，解决了一些类型无法作为参数的问题。最后，她展示了如何根据类型的大小对type_list中的类型进行排序。

As you may have heard by now, Ranges got merged and will be part of C++20. This is huge news and represents probably the biggest shift the Standard Library has seen since it was first standardized...

Disclaimer: these are my early thoughts. None of this is battle ready. You’ve been warned. Hello, Coroutines! At the recent C++ Committee meeting in Toronto, the Coroutines TS was forwarded to ISO...
