V8 team will start working on generators

I think generators have the potential to greatly change how node.js code is written (for example it could look like this http://taskjs.org).  However, it depends on many factors:

1) How easy will it be to migrate existing node.js code?  It seems that most of the community has decided that a simple async library (https://github.com/caolan/async) is good enough instead of promises.  So it may be difficult to migrate that to something like tasks.js or anything else using generators.

2) Since node.js developers are used to chaining callbacks and using async library, there may be a lot of inertia to overcome before generators can have much impact.

3) What kind of impact, if any, will generators have on the core node.js API?

We won't be switching over right away, if that is what you mean.
We'll probably let user modules duke it out first, see what works and
what doesn't, then steal^Wuse that as a source of inspiration.

Generators have some nice applications. Like iterators and such.
I wrote https://github.com/Floby/node-object-iterator to return a generator and it was sometimes a pain to keep states and such.

Good news!

For us the migration be a one line code change! Will be interesting to compare the performance between generators and callbacks.

Reference please?

He was probably talking about node-fibers
