INN marks such "windowed" scalars as read-only, which I think only makes sense for that situation. I guess I could think of cases where you might want to do in-place modifications without changing the allocation, but that sounds a lot iffier. -- Russ Allbery ([EMAIL PROTECTED]) <http://www.eyrie.org/~eagle/>
