I think that this arises from a confusion as to what a "value" is in
"pass by value".

The point of it being pass by value is that there is no statement you
can execute in the function that has the effect of an assignment of the
expression that was passed in from the caller. This holds no matter what
kind of object is passed in or what mutable properties it has or does
not have.
