[webkit-help] What's the use of Structure for non-JS classes?

[Jiho Choi]

Hi,

I found out that Structure is created for non-JS classes (mostly when
creating a VM instance), even for Structure itself. Is it there because
such classes inherit from JSCell? And I guess they inherit from JSCell to
make themselves GC'ed properly, right? If then, my question is whether
those Structures are ever transitioned. I guess not. Could someone clarify
these please?

Thanks,
Jiho
