You definitely can do this. I think it's just __dtor.  But I'm not sure if  
that calls the whole chain.  rt_finalize, the function that actually calls  
the dtors calls each dtor in the chain individually.  You can see how it  
works here:

However, if C is calling your dtor, I'd highly recommend *not* using GC  
memory for your class data, you can std.conv.emplace it in C-malloced  
memory.  If it has any references to GC data, use GC.addRoot to make sure  
that data isn't accidentally collected, and use GC.removeRoot before  
destruction.
