[antlr-interest] grammar question

[Matt Benson]

If I have a rule that wants one of each of three
subrules matched, is there any shorthand to require
this without imposing order?  The following would be
the long version, I suppose:

top
  : a b c
  | b c a
  | c a b
  | c b a
  | a c b
  | b a c
  ;

-Matt
