Slime for Vim
I just saw this announcement on reddit about getting Slime running on Vim. We've heard it all before, of course, but it looks as if it's real this time. As I've said before, I moved to Emacs after a lifetime of Vim use specifically to get Slime so I should be annoyed but I'm not. Emacs has so much to offer—especially the marvelous Org-mode—that I don't regret the move at all.
Nonetheless, this is great news for Lispers who refuse to give up Vim. Slime makes developing with Lisp much easier and getting that capability without giving up their preferred editor should gladden the hearts of Vim Lispers everywhere.
