That shouldn't even be necessary. That just creates the semantic problems we have. It could be as simple as

That reminds me. What about category unions?
Rick Block and I spent some time discussing the syntax for intersections (see [[Wikipedia:Category intersection]] or the shortcut [[WP:CI]]). Since there can be more than two categories involved, and you'd still want to pipe how it was displayed, we came up with:
[[:Intersection:Actors::Americans::Living people|Living American actors]]
You're right. That's better, because you don't always have to have link text (though you probably should).
The only thing missing would be unions of only some of the subcategories, for instance, the union of Comedy films and Drama films, or Poets and Novelists. For most topics these do not seem very significant.
I'm fairly sure people would come up with uses. It shouldn't be much additional work to do this if intersections are already being done.
