From v5.6.0, group designators may also be lists of notes, either explicitly
or implicitly computed by an expression equating to a list enclosed in double-quotes:
Note in the latter example how string literals within the expression use single-quotes to avoid premature closures.
Another new option is a list implicitly computed by a find() query expression:
Note that find() queries do not need to be double-quoted, unlike the earlier examples above.
