+        string name = null;
+        
+        public string MyNamedArg;
+

+        public SimpleAttribute (string name)
+        {
+                this.name = name;
+        }
+        
+        public string AnotherArg {
+                get {
+                        return secret;
+                }
+                set {

+
+		public object D;
+}
+
+[Simple ("Fifth", D=new double[] { -1 })]
+class Blah2
+{
+}
+
+public class Blah {
+
+        public static int Main ()
+        {
+				object o = (((SimpleAttribute)typeof(Blah2).GetCustomAttributes (typeof
+(SimpleAttribute), false)[0]).D);
+				if (o.ToString () != "System.Double[]")
+					return 1;
+				
+				Console.WriteLine ("OK");
+                return 0;
+        }

+isProperty, Object& value, Type& type, Boolean isLast)
+   at System.Reflection.CustomAttribute.GetObject()
+   at
+System.Reflection.CustomAttribute.CheckConsistencyAndCreateArray(CustomAttribute
+caItem, Type caType)
