Got it!

==========
$ cat /tmp/foo.ecl
ecl << EOF
(let* ((s (make-string-output-stream))
        (*standard-output* s))

   (format t "Buffers: ~{~A~^, ~}"
     (mapcar (lambda (buffer) (vim:buffer-name :buffer buffer))
             (vim:buffers)))

   (vim:msg (get-output-stream-string s)))
EOF

$ vim
:source /tmp/foo.ecl
<ee>
Buffers: NIL
==========

Second time I :source /tmp/foo.ecl, I don't get the <ee>, though. Any 
ideas there?

To change the topic slightly: I might try to add if_ecl.* (and not the 
network/asynch patches) into the official Vim tree.

Would any of the original authors object? Tried getting hold of Eirik, 
but no response to the ntnu.no address I used. (I hope at least some of 
the others are lurking here on the list still).
