+Summary: More implicit casts not considered with compound assignments
+
+Description of Problem:
+
+Weird case not fixed by bug80313:
+
+using System;
+
+namespace Bugs
+{
+    class Bug2
+    {
+        struct MyByte
+        {
+            private byte value;
+            public MyByte(byte value)
+            {
+                this.value = value;
+            }
+            public static implicit operator MyByte(byte value)
+            {
+                return new MyByte(value);
+            }
+            public static implicit operator byte(MyByte b)
+            {
+                return b.value;
+            }
+        }
+
+        public static void Main(string[] args)
+        {
+            MyByte b = 255;
+            b += 255;
+            Console.WriteLine(b);
+        }
+    }
+}
+
+Assignment "b += 255" fails although 255 is implicitely
+convertible to MyByte.
