Re: streams are cool, you could stream virtually anything!

Actually I plan a `stream-push' - why not?  There is nothing wrong with
that; `push' itself doesn't modify any list, it just sets the PLACE to
the newly created cons
  
  (cons NEWELT PLACE)

We can do the very same for streams; just use `stream-cons' instead of
`cons':

--8<---------------cut here---------------start------------->8---
(defmacro stream-push (newelt place)
  "Add NEWELT to the stream stored in PLACE.
This is equivalent to (setf PLACE (stream-cons NEWELT PLACE))."
  `(cl-callf2 stream-cons ,newelt ,place))
--8<---------------cut here---------------end--------------->8---

Would that be ok?
