C++ programming question, godbolt link below. I’m computing std::strings at compile time via nested function calls, and due to the constexpr rules, I can’t leave the result in heap allocated storage. So I’m using a std::array to store the result and I use the size of the computed string to initialise it. Ideally I’d like to put that in a function, but the constexpr rules force me to use a horrid macro. I can’t think any other way to do it.
