I don't think that there is any guarantee that iteration via cursor will
actually work for an unordered (hashed) container. In practice, it usually
will work, but there is nothing in the standard that requires that (unless
"there are no intervening operations", but that would be a pretty useless
iteration!).
Cursors also have uses that have nothing to do with iteration, of course.
