"for of" is actively being added to V8. It should not be very long before it lands in V8 (and thus in Node). I don't like the idea of another keyword that at best acts exactly the same (or at worst acts subtly different).

CoffeeScript already has an of operator (like js in) and an in operator (array like iteration) neither of which could easily be made to both (I think). So we'd probably need a new name. Once "of" is in V8 we can compile to it directly though.

It's not clear to me how to compile directly to it without breaking CoffeeScript code that already uses for/of. Is the idea to break compatibility with existing CoffeeScript code?

See my longer question about this upthread.

I honestly don't know, this was just a quick hack this morning while I had a hangover :) I think it's good to have the conversation though!

I'm not current on what kind of compatibility coffeescript is trying to keep, but IE6 certainly not going to like the newer V8 features...
