+Bug#: 79070
+Product: Mono: Compilers
+Version: 1.0
+OS Details: 
+Status: NEW   
+Priority: Normal
+Component: C#

+TargetMilestone: ---
+Summary: Implicit conversion to decimal on both operands
+The following code will compile with Microsoft csc, but mcs aborts  
+compilation with "test.cs(9,34): error CS0019: Operator `+' cannot be  
+applied to operands of type `MyDecimal' and `MyDecimal'". The same code  
+works with mcs if I change decimal to int, so (for whatever reason, I 
+couldn't find one in the C# specification) this behaviour depends on the 
+class MyDecimal {   
+    public static implicit operator decimal(MyDecimal i) { return 42; }   
+class TestProgram {   
+    static void Main(string[] args)   
+    {   
+        MyDecimal a = new MyDecimal(), b = new MyDecimal();   
+        System.Console.WriteLine(a + b);   
+    }
