Ops, by the way: we can't use a Java array to implement a RPython list because
you can't resize Java arrays.  So there is an extra indirection even in Java
and there is a need to remove it with enough analysis and optimizations...
Or am I missing something?

In Lisp you can declare resizable arrays, though it may mean an extra
indirection too.
