In the case of binary operators, we have three cases -- free function, friend function, member function, that all generate slightly different ASTs, so I believe we should try to cover them all.
But those all regard the operators declaration. 
Here we test the operator call expression - `CXXOperatorCallExpr`.

I think we should test friend function declarations when we add support for them in the tree, and then we add tests for declaration of friend operators, friend member functions and whatnot.
