c++ - constexpr const vs constexpr variables? - Stack Overflow

WebFeb 21, 2024 · A constexpr function is one whose return value is computable at compile time when consuming code requires it. Consuming code requires the return value at compile time to initialize a constexpr variable, or to provide a non-type template argument. When its arguments are constexpr values, a constexpr function produces a compile-time constant.

Webconstexpr is a contract. If it were deduced from the function body, you could non-obviously break the interface by changing the implementation.
