I tried using this code, and at first it worked. But when I create a production version (minifying the whole code), it somehow removes almost all CSS classes (including the layout bootstrap).
Luicaps,
Try RegExp(':hover') instead /:hover/

nice solution. one problem is that if you have a hover state that is the same as another class, you will lose the styling when that class is applied. e.g:
&:hover, &.active {
some:style
}
if the applied element has the active class, the rule will have been deleted.
