+Description of Problem:
+
+> Hi again hackers,
+> 
+> I've noticed I can explicitly implement an interface method as virtual
+> and I've read that it's not legal. Is that a bug in the mcs?.
+> 
+> I mean, f.ex:
+> 
+> interface IMailAgent
+> {
+>       void Send(object obj);
+>       ...
+> }
+> 
+> ...
+> 
+> public class GroupWare : IPhoneable, IMailAgent, I...
+> {
+>       public virtual void IMailAgent.Send(object obj)  // I can
+>       {                                                // compile this
+>               ...
+>       }
+> 
+>       ...
+> }
+> 
+> What I've read is that that I can't mark a method as virtual 
+> if it's an 
+> explicit implementation of an interface method. Actually I can do that
+> with mcs.
+
+
+Steps to reproduce the problem:
+1. Try to explicitly implement an interface method using the virtual modifier.
+ 
+
+Actual Results:
+I can do that.
+
+Expected Results:
+It's not legal to use access modifiers (public/protected etc..) or any of
+abstract, 
+virtual, override, or static modifiers either.
+
+
+How often does this happen? 
+Always.
+
+Additional Information:
+More on mono-list.
+
+Ask me for testing code to see this bug and I will mail you it.
