I'm borrowing these words from the BeBook:
"due to the peculiarities of C++, overriding any version of an overloaded
function hides all versions of the function".
So, in order to access the hidden function you can either explicitly call
A::function1(x, y, z), or have function1(int, int, int) implemented in class
B again.
