Hmmmm, can you explain how multiple subtractions in scopes work?

I assume you’re talking about something like:  
source.ruby - string - text.html.basic

Two questions:  
(1) have you seen this come up in practice, and where?  
(2) How are you interpreting this? As  
source.ruby - (string - text.html.basic)  
or  
(source.ruby - string) - text.html.basic  
or as something else entirely?

Yes, I see them now. OK thanks for the tip.

Well, I’ve found them while debugging the Brilliance themes in  
ultraviolet, they include many uses of this.

As

(source.ruby - string) - text.html.basic

To be more precise: if any individual scope which is preceded by a  
minus sign matches, then the score for the whole expression is zero  
regardless of the non-minus matches.
