+Version: 1.1

+TargetMilestone: ---
+Summary: Implicit conversion to decimal with unary minus
+While my previosly reported bug #79070 (Implicit conversion to decimal on
+both operands) is fixed in, the following code still doesn't work
+for me (it works with csc). The error message is "unary.cs(8,30): error
+CS0023: Operator `-' cannot be applied to operand of type `MyDecimal'".
+Again, mcs will compile successfully when using int instead of decimal.
+class MyDecimal {
+  public static implicit operator decimal(MyDecimal d) { return 42; }
+class Unary {
+  public static void Main() {
+    MyDecimal d = new MyDecimal();
+    System.Console.WriteLine(-d);
+  }
