But in general, at this point, with D, if you want
deterministic destruction, then you use structs. Classes are
not the appropriate place for it. If they were ref-counted,
then they could be, but as long as they're not, then classes
are not the place to have stuff that cares about deterministic
destruction. And if you're stuck with stuff in classes that do
care about deterministic destruction, then you have to use the
sort of solutions that C# and Java use where you don't rely on
the destructor/finalizer to clean anything up except for the
cases where you screw up and forget to manually call the
function that does the cleanup.
Unfortunately, it is quite common to need both virtual functions
and deterministic destruction. It isn't helpful to disregard the
problem by saying "you should have used a struct", in many cases
it's not any easier.
