Can I get a count of distinct values in multivalue field?

What I'm looking for is a hybrid of the stats list() and values() functions. First, I'd like the list of unique values for a multivalue field, then alongside each unique value, I'd like the count of occurrences of that value. Is this possible?

Maybe this is better illustrated through an example.

Given a set of events like this:

03/12/2013 15:55:00 id=foo abc=123,123,123
03/12/2013 15:56:00 id=bar abc=123,456,789,789

I can get tables like these with the list() and values() functions, respectively:

  id     abc               id     abc
----------------         ----------------
 foo     123              foo     123
         123              bar     123
         123                      456
 bar     123                      789
         456
         789
         789

But what I really want is this:

  id     abc    
----------------
 foo     123 (3)
 bar     123 (1)
         456 (1)
         789 (2)

I believe this to be possible... for a search query superhero (which I am not). :)
