Last week, Chandler Carruth announced Carbon, a potential C++ replacement they’ve been working on for the past two years. It has the usual cool features you expect from a modern language: useful generics, compile-time interfaces/traits/concepts, modules, etc. – but the thing I’m most excited about is a tiny detail…
(Most) C++ implementations provide at least 8, 16, 32, and 64-bit signed and unsigned integer types. There are annoying implicit conversions, discussions about undefined behavior on overflow (some think it’s too much UB, others think it’s not enough), but for the most part they do the job well. Newer languages like…
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution. In both cases you restrict yourself to the subset of C++ that works on your target platform, use conditional compilation if your code…
