"As in all languages in the C family, everything in Go is passed by
value."

C++ clearly has what it calls "references", and parameters can be of
reference type.  If you want to argue that C++ doesn't really have call
by reference, I suggest basing your argument on a document that Ken
Thompson may or may not have had any hand in writing, and that could
easily have a mistake.  I also suggest you do it elsewhere.
