Description

There are a few cases where bare array initializers are not yet supported:

1. int[][] array = { {1,2}, {3,4} };
2. @Target({ ElementType.FIELD, ElementType.METHOD })

3. @interface A {
     String[] strings() default {}
   }
   

These were implemented as part of [1] but the PR was closed. It may be worth looking back over what was done and re-implementing one or more of these cases. It was noted that Closure[] array = {}; is one of the edge cases that leads to ambiguity.
