If you have a constant expression like 1 + 2 in your code you can evaluate it at compile time once and avoid computing it at runtime. You can do that with control flow and much more complex language constructs in C++. If you want to know more about that look into C++ template meta programming, constexpr, and constval.

    I get that the designers wanted to have compile time static replacement but this was not the way to do it.

    It’s easy to build a well-designed language when you don’t have to work around the mistakes of the past that were too difficult to solve then and too deeply entrenched to change now.
