While working on my answer to this question, I came across the situation where I'd like to match multiple scoreboard tags at once, i.e. do something like
/tell @a[tag=Great,tag=Awesome] You are a great and awesome person!
The above command does not work as intended (tested on snapshot 15w45a), since the second
tag target selector argument overwrites the first (the same behavior as on every other argument). This means that simply awesome (but not great) persons are called awesome and great, rather than those that are both awesome and great!
Is there a way to include multiple tag matches into the same target selector?
