I have a mesh, and a bunch of type instances I want to attach to its type instance. The number of attachable objects should be unlimited. My plan is to have a list of the Handle of each of the attached Type intances connected to each mesh (a different list per mesh), and I'm trying to figure out how best to do this. I don't think a Bank will work because it doesn't appear to be possible to delete single items (though it is probably the answer to this problem, if there's a way around that), and a chain of Types would be crowded and silly seeming. So how is the best way to make an unlimited chain of handles within my mesh's Type instance?
