I might be mistaken but isn't it the case now that class dtors
may never get invoked by the GC anyway? In which case having
class dtors is pointless because one cannot rely on them.
But dtors for structs I thought would still be useful. The dtor
might not be called by the class dtor as it no longer exists, but
it is called if I reassign the struct member by value.
C c = new C();
// some code
auto s = SomeStruct(/*with some parms*/);
c.setStruct(s); // the existing c.struct dtor will be called,
releasing whatever resources it needs
