Overload resolution

Overload resolution takes place after the compiler unambiguously finds a given function name. The following example demonstrates this:

struct A {
   int f() { return 1; }
};

struct B {
   int f(int arg) { return arg; }
};

struct C: A, B {
   int g() { return f(); }
};

The compiler will not allow the function call to f() in C::g() because the name f has been declared both in A and B. The compiler detects the ambiguity error before overload resolution can select the base match A::f().
