I'd go as far as to suggest that if you need to make heavy use of such
a feature, either your styling is abitrary, and therefore confusing to
a user, or you have failed to use:

- classes (in particular, note that a single element may belong to
  more than one class, although that is not an invitation to 
  have a class per font!);
- inheritance;
- cascading;
- multiple selectors for one rule,

properly, or failed to provide a HTML that describes the true document
structure.
