Implements js2r-kill

[NicolasPetton]

Probably not ready to be merged. Expect rough edge-cases :)

[NicolasPetton]

There are still some rough edge cases like the following:

function foo(bar|, baz) {...

If I kill, I would expect to have:

function foo(bar) {...

The question is if it's worth the effort (we have the same issue with if statements, for statements, etc). My guess is yes :)

[NicolasPetton]

I think it's in a decent shape now.

At the end I went with the following strategies:

• if we are in a comment node, just kill the line
• if we are in a "balanced" JS node (array, object, string), use the AST to kill
• else fallback to list manipulation
• on error, kill the line

Excellent work! Thank you. This is something I've been wanting for a while. I can finally go back to coding javascript now. ;-)

[NicolasPetton]

thanks! I want raise-expression now. It's the other killer feature of paredit that I also want everywhere else :)

[magnars]

Sounds great. :) I think your work on this feature was excellent, and I'm really appreciating the thorough tests you've added. So, I've added you as a collaborator to the project. Welcome to the team!
