Now I change the class A to become :

class A {
    void fun() const { ... }
    void fun() { ... }
}

And suddenly, the override doesn't override the same thing anymore.
Which is unnacceptable.

You didn't try to actually compile this, did you? ;D

You can't compile that now, can you?

Exactly, it won't compile. It was an explicit measure to prevent this 
form of function hijacking.
