+Summary: foreach fails in iterators.
+
+A couple of statements require local variables (like foreach).  These local
+variables should be morphed into an instance variable of the generated
+classes to keep their state.
+
+For instance, the following program will fail with iterators:
+
+using System.Collections;
+
+class X {
+	static IEnumerable A (int [] a)
+	{
+		foreach (int b in a)
+			yield b;
+	}
+	
+	static void Main ()
+	{
+		foreach (int a in A (new int [] {1, 2, 3})){
+			Console.WriteLine ("-> " + a);
+		}
+	}
+}
+
+Instead of crashing, it should print 1, 2, 3
