New issue 2355 by longs...@gmail.com: Implement `yield` for generators
http://code.google.com/p/v8/issues/detail?id=2355

Generators have been approved for ES.next:  
http://wiki.ecmascript.org/doku.php?id=harmony:generators

Firefox currently implements the `yield` keyword, but not the function*()  
{} syntax. I think v8 should do the same for now.

I searched everywhere and I can't find any existing bugs or plans for the  
`yield` keyword. This is a significant feature for javascript, one of the  
few that introduces a new semantic that is very difficult to simulate  
without native support.

This would have a big impact on node.js as well, allowing better style for  
async code.

+1. While for some people this will be just a "nice to have", for complex  
JS code and especially in node.js it would make all the difference in the  
world. It will enable people to write coroutine-like code instead of crufty  
and sometimes convoluted callback boilerplate.

Edit: forgot to add - for example, something like task.js  
http://taskjs.org/ + V8 would mean pure awesome (especially for node)

All I can say is ... what's the hold up?  Firefox has had this for 5 years  
now.  You guys could at least make it conditionally compiled so that  
node.js can use it.  And while I'm dreaming maybe you could implement  
the 'async' keyword?  Of course that would mean having a task framework  
like .Net, which would imply having a standard framework period.

I wish someone could at least explain why generators are not being  
implemented in V8.

I would give all Harmony features for only the support for generators. I  
believe it will bring ssjs to a comletely new level. So... WHEN??? :)

Please, for the love of all that is good, yes. Sooner than later.

Please make it an expression  so one can conveniently pass a value to  
generator, e.g.:

   var x;
   x = yield;

or

   return yield MyAsyncFunction();

The specs already has yield as an expression, so they should implement it  
that way.
