When entering a class destructor, are any of the dynamically

No. The order in which the GC deallocates objects is not
defined, and when the dtor is run, any references to
GC-allocated objects cannot be safely read, as those objects
may have already been destroyed.
Does this deviate from the way C++ handles destruction?

" Can I use this in a destructor
Yes.
For example, I know I'm not supposed to do anything with base
classes, since they are gone.
No, the base classes are still intact at this point. Members (and
perhaps other base classes) of derived classes have already been
destroyed, but members and base classes of this class remain
until after the destructor has finished."
I thought that also in D all the members and the base objects of
the object which is destructed are still valid and accessible
until the destructor finished.
