Although C++ can be ugly, one reason I keep going back to it

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.

To add to what the other people said,
there exists scoped!T in std.typecons to allocate a class on the
stack, and Unique/RefCounted as you mentioned. AFAIK refcounted
is in the process of being overhauled, but the user should notice
no differences.
