No, whether the _language_ is pass by value or pass-by-reference has
_entirely_ to do with it's definition.

Now you're talking about how you can implement higher level constructs
using a language that doesn't directly implement such constructs. You
might as well say that C is a linked-list language like Lisp since you
can write a linked list implementation in C. If you said that you'd
be just as wrong as saying that C uses call-by-reference.
