+// 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.
