This doesn't even need friending.
#include <iostream>
template <class T>
struct qEmit
{
T* that;
qEmit(T* it) : that(it) {}
T* operator->() {return that;}
};
struct X
{
void sig1() {std::cout << "sig1\n";}
void sig2() {std::cout << "sig2\n";}
void foo() {
qEmit(this)->sig1();
qEmit(this)->sig2();
}
};
int main()
{
X x;
x.foo();
}
