I have to disagree. There's always a need to pass an object by value when you want to be sure that the
called function will not modify the original object. Otherwise, the constness of the param object cannot be assured.

Another case when this is necessary is when you're using classes that you cannot change. So, good or bad design,
they cannot be changed and you need pass by value... which is not possible in VFP.
