what do you want a, b, and r to be?

Maybe the values 1, 2, true the first time, and 2, 1, false the second?

If so:

#((1 2 true) (2 1 false)) do: [:row |
   [:a :b :r | "do something useful" ] valueWithArguments: row.
].

Beware... if your row doesn't have exactly three values, you'll
get an exception.  If you don't want that, consider #valueWithPossibleArgs:
