Lambda the Ultimate

Are there any good bodies of such programs perhaps ideally which are pure that can be used for research studies? I am trying to get a sense of how scheme/lisp routines are typically structured without having to construct a body of my own routines which may be a non trivial task.

I have my own programming language (these days who hasn't?), and would like to learn what would be the best way to promote it. LTU publishes conference materials, but usually after the fact. I understand that submitting something to JVM language summit can give the project some visibility, but it it is at least half a year away... What other conferences you recommend?

P.S. I'm submitting my stuff to SIGMOD/PODS but this is within database community. Sadly, there is not much communication between PL and database people.
