The introduction of the “constexpr” feature in the C++11 standard has raised a great interest in the compile-time function execution in the programming languages communities. In this paper, we evaluate this feature and argue that while the compile-time evaluations are valuable optimization methods, its explicit support on the level of a programming language is a wrong decision. We show that compile-time evaluations must be enforced by the compiler automatically and transparently to the developer. Finally, we propose a programming language design principle stating that positive optimization “hints” must not be a part of programming language.
