With more thoughts, just for emphasis, I think the colon as a conditional is wrong:

```.mixin(@a: 4) when (@a: 3) { ... }```

The reason is because you've (and CSS) established the colon as an assignment operator. So I think = should be the comparison operator. In other words, as I think about it more, I think the media query syntax is actually, in truth, kind of really stupid. It's inconsistent with the language. But the other stuff about parentheses and keywords I'm still in support of.
