+// The purpose of this test is to detect that closures in [LocalInitializer]s |
+// and [FieldInitializer]s are properly converted. This test assumes that |
+// [ArgumentExtractionForRedirecting] transformer was run before closure |
+// conversion. It should introduce one [LocalInitializer] for each argument |
+// passed to the redirecting constructor. If such argument contains a closure, |
+// it would appear in a [LocalInitializer]. The [FieldInitializer] example |
+// requires no such elaboration. |
