Well, the convention in theory is usually that `object->method(param)` is equivalent to `method_function(object, param)`, and likewise you have the signature of `method(self, param)` in languages where `self` is an explicit argument—if only because it's always present so makes sense to always have it first. Thus, translating an OOP builder would make the functions `addThis(object, param)` =) With the difference in my proposal that the object is treated as a COW.
