NIL

[Adam Alpern]

You might run into some confusion - there's already a NIL out there. It
stands for New Implementation of Lisp. It ran on VAXen I think. Any good
history of Lisp should cover it. 

Perhaps LIN could be a candidate  - Lisp In the Nineties? Nah, that
would be planned obsolesence. 

Continuing in the recycling of old acronyms, perhaps NCOMPLR - New
COmpiler for Major Proactive Lisp Resurgence? Then our motto could be:
"This is insane. What we clearly want to do is not exactly clear, and is
rooted in NCOMPLR" (http://www.best.com/%7Ethvv/lcp.htm)
