First, this doesn't break with the practice that argument attributes are copied/applied to each call site, `byval` is still present at both the call site argument and the argument. It does state however that the pointer of the attribute is pointing to something different for the call site argument and for the argument. That is no different to the current semantic, as far as I can tell, just spelled out. Do you object to say that the call site argument and the argument point to distinct memory locations or something else?
