Sorry about that, let me explain it at a higher level. I'm looking to make a runtime-defined GC'd struct. Some members will be GC'd others will be primitive. So I have a definition that says:
Foo {member1=int, member2=Object, member3=float} >From what I can tell I can't create lltypes on-the-fly at runtime, so I'm left laying out the memory for this by hand, and making a custom GC hook. But I'm still figuring out how to do that.
