   I must admit I don't understand your example. R4RS and R5RS state
that the argument to ,@ (unquote-splicing) must evaluate to a list, and
(1 2 . 3) obviously doesn't. It might be an extension to the standard,
but then I need a proper example of what the expected behaviour is.

   All efforts and contributions are welcome. I set up a mailing-list
for Elk (Cc:ed) and will put archives online this afternoon. If you want
to subscribe, just send a "subscribe elk" message to ecartis@lists.zoy.org.

   I saw mention of this in this paper:

  http://www.ircam.fr/equipes/repmus/Rapports/PeterHanappe99/ch4/node2.html

   I will try to contact the authors, they seem to have done additional
work on Elk, such as thread-safety.
