Right, and it will be done if I write, e.g.
(with-open-file (stream ... )
(iter (for x in-stream stream)
(foo x)))

Iterate already has a mechanism for this: the in-file driver, which
already does (and should) close the stream.
The point is, when you pass a stream to the driver, iterate doesn't
know what the stream is, what you want to do with it, or anything. Why
should it close the stream, especially when streams are generally
created inside UNWIND-PROTECT-based macros?
