-Any rule that uses a:hover will also work for .hoverlink, even if they have other selectors as well

-    >> print css.compile('''
-    ... @option compress:no, short_colors:yes, reverse_colors:yes;

-Sometimes a selector sequence extends another selector that appears in another
-sequence. In this case, the two sequences need to be merged.
-While it would technically be possible to generate all selectors that could
-possibly match either sequence, this would make the stylesheet far too large.
-The simple example above, for instance, would require ten selectors. Instead,
-Sass generates only selectors that are likely to be useful.
