By yuchi:

I personally don't like the optional parameter, it's something completely not semantic. You will need something like:

```stylus
color: mix(red, main_color, 30%, true)
```

What does that true means? should we use a predefined literal like `all-channels`? I've not seen something like that in stylus and IMHO it's horrible.

Pinging @visionmedia, and waiting it's *answer* on the *querelle*. I'll gladly correct this PR with whatever comes out of this discussion.
