You might prefer to also wrap them in a class or namespace so they aren’t polluting the global namespace. http://www.vishalchovatiya.com/when-to-use-const-vs-constexpr-in-cpp/

C++ constexpr: What It Really Is? by Debby Nirwan
Web2 days ago · Type erasure is where the type of an object is hidden so that the object can be utilized in a type-independent manner. Type erasure is extremely useful in several scenarios, including heterogeneous containers (containers that store objects of different types), and using objects generically through common interfaces. WebIn Part I of this blog series, we covered how to convert our type name to a string, how to safely store type-erased objects, and how to handle trivial types (AnyTrivial). In Part II we covered how to manage type-erased storage of general types (AnyOb... Webvirtual const char* what() noexcept; 而它在std::exception聲明為： virtual const char* what() const noexcept; 並且簽名的這種差異意味着當它被std::exception的處理程序捕獲時，它調用std::exception::what()而不是except::what() 有幾點值得一提： 確保您的函數重載與基類中的重載完全匹配。 mc thimble\\u0027s
