But there's no guarantee that it would be any faster.

Not always. eg:
#include <iostream>
constexpr int func(int cnt)
{
int val = 1;
while(--cnt) val *= 2;
return val;
}
int main()
{
constexpr int val = func(10);
std::cout << val << std::endl;
return 0;
}
In C++14 and onwards func() will literally be run by the compiler at compile
time and the result hard coded into the binary. No C compiler can do that not
because the language couldn't do it in theory, but because its never been
specified in the standard.
