I have seen code like this:

void func()
{
    constexpr int c = 1;
    f(c);
}

For some reason, people believe that adding constexpr will magically 
improve optimization. In reality, it doesn't change anything compared to 
const and often reflects a misunderstanding of how the compiler works. 
As a result, I end up having to explain it. In this sense, constexpr is 
viral and spreads confusion.
