[literal group assignment lists]

From v5.6.0, group designators may also be lists of notes, either explicitly

$Color(/config/one;/config/two)="red" 

or implicitly computed by an expression equating to a list enclosed in double-quotes:

$Color("collect_if(all,$Path,$Price>5)")="red" 

$Color("collect_if(all,Color='red',$Path)")="blue" 

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: $Color(find($Price>5))="red" 

$Color(find($Color="red"))="red" 

Note that find() queries do not need to be double-quoted, unlike the earlier examples above.
