RAII and Deterministic Destruction

Although C++ can be ugly, one reason I keep going back to it rather then
commit more time to reference-based languages like C# is because I like
deterministic destruction so much. My question is whether D can REALLY
handle this or not. I've not been sure about this for some time so now
I'm just going to come out and finally ask.
I know about this RAII section in the documentation:
http://dlang.org/cpptod.html#raii
But I don't believe that handles all cases, such as having classes as
member variables of other classes. (Do the members get destructors
called too?)
Then there is std.typecons.Unique and std.typecons.RefCounted. With
these, can I really get deterministic destruction for all cases like I
would in C++?
If so, it might be a good idea to emphasize this more in the
documentation because I'd think people coming from C++ would be looking
for this.
