should be able to return a postcss plugin

[MoOx]

var cssnext = require("cssnext")
typeof cssnext === "function" // should be true

why not expose it like features is exported, e.g., css-flip?

[MoOx]

This issue was a reminder but can be handled this way (by return a postcss plugin).
So yeah, the idea is to expose.
I've already done that I think https://github.com/cssnext/cssnext/blob/master/index.js#L69
But I want to add a simpler way to add plugin before or after some other (to allow perfect control).
Maybe an API like addFeature(), insertFeatureBefore() & insertFeatureAfter() can help ?

FYI, here is the blocker postcss/postcss#74

[MoOx]

Well, we can forget this idea, people can use plugins by themselves.

[necolas]

hmm, i think exposing it as a plugin would be pretty useful and easy.

[MoOx]

Can't be done for now. I'm waiting for a postcss change here to make this happen postcss/postcss#74 (please give your opinion over there @necolas :)
But maybe you are right, this would be nice.

Ok I've made a pr so postcss.use() can consume plugin of another postcss instance.
postcss/postcss#115

This PR is merged in tokenizer branch (future v3).
As soon as v3 is released, we might be able to do this

postcss.use(cssnext()).use(whatever).process()

I just need to return postcss instance when there is no string given has a first param to be ready for that :)

[MoOx]

Done.
I'll just close this issue when postcs 3 is out.
