when.js and generators

[Peter Mucha]

i am currently using when.js in several projects and i like to stay there. but currently, i am moving forward to use generators + promises (like described at Q's documentation). will there be any support for this in when.js?

Hey Peter,

I actually have an open pull request for this feature: https://github.com/cujojs/when/pull/206

If you're willing to give it a spin, I'll merge it to the dev branch asap, so you can try it out.  It's similar to the existing when/function module: it includes both a "lift" function that transforms a generator into a promise-returning coroutine, and "call/apply" for immediately executing a generator as a coroutine (returning a promise for the ultimate result).  Do those features cover what you need?  If not, let me know and I'll be happy to discuss others that you might need.

sounds great, i would really like to try this out. the code looks like it fits my needs (especially the throw-support).

Cool. I just rebased the es6-generators branch onto latest dev and pushed it: https://github.com/cujojs/when/tree/es6-generators

Give it a go and let me know how it works for you.  It'd probably also be good to move the discussion over the to pull request--I'd love to capture your feedback there, as well as any problems you find so I can fix them as part of the pull request.
