On a related note, why doesn't __traits(classInstanceSize, T) consider the padding bytes? If I'm not mistaken struct sizes do include the padding bytes. The following class has the very odd size of 17! Is that by design?
Probably it's because classes are intended to occupy their own memory block, so the pad doesn't matter, you can't put two in the same block anyways.
If you want to do it, I think it should be possible. But I don't think it would work great if you put two classes in the same block without significant compiler/GC changes.
That being said, given that all GC blocks are at least 16-byte aligned, the same should hold true for any class instance.
