      Description

      Let's say we have the following enum declaration (in Java):

      @interface Person {
      String[] friends();
      }

      In Java, curly braces may be omitted if a person has just one friend:

      @Person(friends="Joe")
      class Jane {}

      In Groovy, this gives a compile error:
      Annotation list attributes must use Groovy notation [el1, el2]

      Of course @Person(friends=["Joe"]) still works, but it would be nice if Groovy also supported the abbreviated syntax.
