> Looking at the editor draft for CSS3 hierarchies (http://dev.w3.org/csswg/css3-hierarchies/) one thing that bothers me is the excess of ampersands. Would using @-rule syntax avoid this necessity?

> The ampersand could be re-purposed solely as an optional positional symbol as some preprocessors use it:

> @prefix .module {

> ššš &.alt {

> ššš ššš }

> .module.alt { color: purple; }
> .hasJs .module { color: red; }

> Another thing that concerns me about nesting in general is the lock-in that means no rules can be repurposed outside of a nested block; Introducing another symbol to compliment the ampersand could enable an opt out:
