It definitely is. I was just talking about the definition of "an object."

It separates the functionality from the object. Turns it into an external stimulus to change the state of an object.

I used this pattern, back in the 1990s, to make a C API behave like a C++ API. This was back when every compiler had a different stack convention, and the only one we could rely on, was C.

To be fair, I did have function pointers, in some of the objects, that acted as "poor man's vtables."

I know that the API was still in use, 25 years later.

It's possible that we are talking at cross purposes.

I think you might be arguing that the object itself does not include the set of functions/methods/operations that act on it, whereas I see them as another attribute of the class/type which is an attribute of the object.
