Deterministic. Pointer based values (Classes, Interfaces) are passed by
reference. Others are by value. An exception to Ansi- and Wide- Strings,
they're passed by reference but when a modification is done the copy on
write semantics will make a copy thus simulating the pass by value. The one
I'm not sure is Dynamic Arrays.
