Also, that's not the correct way to manually allocate a class on
the heap. C.sizeof is the size of a reference to C, not an
instance of C, and we need to blit and construct the instance
before it is safe to use:
import core.memory : GC;
C c = cast(C) GC.malloc(__traits(classInstanceSize, C));
import core.lifetime : emplace;
emplace(c, anyConstructorArgsGoHere);
