Nagging about how preposterous it is to be forced to learn Emacs, is no more.
Frank Duncan has been working on Nekthuth, a Vim plugin for Common Lisp. While it's not completely prime time right now, it certainly looks very promising. Definitively, the most feature-full plugin I've seen so far.
Now if you're one of those few lost souls who just do not want to find absolution in the Church of Emacs, take a look at it and give Frank a hand, or two. For example, make it use Slime's SWANK-BACKEND, not the server, just the portability layer.
Alternatives: Cusp, a plugin for Eclipse. ABLE, a standalone text editor written in Common Lisp.
