+Summary: [GMCS] a little bit more type inference should be performed by gmcs
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+csc 2.0 beta 2 understand code demanding a slightly more type inference,
+than gmcs do currently
+
+Steps to reproduce the problem:
+1. Try to compile following code
+
+
+class list <A> {
+   public class Cons <T> : list <T> {   }
+   public class Nil <T> : list <T> {  }
+}
+
+class C {
+	public static  void Rev<T> (list <T> y) {
+	    if (y is list<object>.Cons<T>)
+		System.Console.WriteLine ("Cons");
+	    if (y is list<object>.Nil<T>)
+		System.Console.WriteLine ("Nil");
+	}
+}
+class M {
+	 static void Main () { 
+	     C.Rev (new list<object>.Cons <string> ());
+	     C.Rev (new list<object>.Nil <string> ());	     
+	 }
+} 
+
+
+2. 
+3. 
+
+Actual Results:
+t.cs(24) error CS0411: The type arguments for method `Rev' cannot be
+infered from the usage. Try specifying the type arguments explicitly.
+abla
+t.cs(25) error CS0411: The type arguments for method `Rev' cannot be
+infered from the usage. Try specifying the type arguments explicitly.
+
+Expected Results:
+clear compiler
+
+How often does this happen? 
+Always
