Here's what the output needs to be:

```
.root {...}
.node {...}
.root .red .node {border-color: red;}
.root .green .node {border-color: green;}
.root .blue .node {border-color: blue;}

```

I expected that it can be done in this way:

```
.root {
    // styles for .root
    ...
    .node {
        // styles for .node
        ...  
        .red & {border-color: red;} 
        .green & {border-color: green;} 
        .blue & {border-color: blue;} 
    }
}

```

but & matches '.root .node' selector.

It will be great to write styles for .node in one block of code.
Is there any analog of & but for local selectors?
May be there is some 'switch' that allows to generate styles accordingly to parent class.
