+You can use them in the same way they would be used in native C:
+
+=begin code
+use NativeCall;
+
+my $just-an-array = CArray[int32].new( 1, 2, 3, 4, 5 );
+
+loop ( my size_t $i = 0; $i < $just-an-array.elems; $i++ ) {
+    say $just-an-array[$i];
+}
+=end code
+
+Which would print the five elements of the array, as it should be expected.
