c++: overriding virtualization

This is a well known technique for me but just recently I heard it was called as 'overriding virtualization'. That's why I decided to expose how calling method from the explicitly mentioned class can override virtualization in classes. Consider you have

class A
{
    virtual void m();
};

class B : public A
{
    virtual void m();
};

When you create instance of class B, you will call B::m in all cases:

A *a = new B;
a->m();/// B::m here

So, if you want to call m from A? Easy:

A *a = new B;
a->A::m();/// A::m here

In the example above I've overridden the virtual call.
