 class X {}
 
+// Closure in field initializer.

I would split this test in two or change the name of the test file (and the
description above in the comment).

+//
 class A {
   X foo;
-  A.named(X foo) {}
-  A(X foo) : this.named((() => foo)());
+  A(X i) : foo = ((() => i)());
+}
+
+// Closure in local initializer.
+//
+class B {
+  X foo;
+  B.named(X foo) {}
+  B(X foo) : this.named((() => foo)());
 }
 
 main() {
   A a = new A(new X());
   a.foo; // To prevent dartanalyzer from marking [a] as unused.
+  B b = new B(new X());
+  b.foo;
 }
