Classes in D do not have destructors. Only structs to. ~this is a destructor 
in a struct, but it's a finalizer in a class. Finalizers are not guaranteed to 
be run, and they can't do anything with GC memory (be it allocating it, 
deallocating it, or using it) unless they're begging for trouble, because the 
GC is free to collect any GC-allocated objects before calling any finalizers 
(which avoids circular reference problems). As such, class finalizers are 
really only good for managing non-GC resources.
