oops, sorry now I see, you want RPython lists to be lists, that's probably different that what we wanted originally.
No, I'm thinking about the following problem: suppose that an RPython list is meant to represent an expensively resizeable array.
that what I was implicitly thinking with "be lists". My point anyway was simply that for Java the first relevant thing is to dinstiguish constant-size lists (the code in listobject uses such things) vs. variable size lists, and both then have natural reprs. In a more subtle approach also lists that have always just _one_ reference to them in the whole heap (and are not passed as parameters perhaps) can likely also be implemented with a direct array reference.
It is true that the generalization and understanding of this kind of criteria is what we need for general structure inlining.
