How about `for (int index, var item : items)`?
For example:
```groovy
// ① traverse a list
List<String> names = Arrays.asList("Alice", "Bob", "Charlie");
for (int i, String name : names) {
System.out.println(i + ": " + name.toUpperCase());
}
// ② traverse a matrix
int[][] matrix = {{1,2}, {3,4}};
for (int row, int[] cols : matrix) {
for (int col, int val : cols) {
System.out.printf("[%d,%d]=%d\n", row, col, val);
}
}
```
