+Summary: The compiler fails because of if/foreach scope bug
+
+Description of Problem:
+
+The following code (although a little ugly) should compile:
+
+if (e.Event.Key == Gdk.Key.Escape) // cancel
+	foreach (Gtk.Widget w in representation)
+		if (w.Name == "new")
+			w.Destroy(); // bye bye
+else if (e.Event.Key == Gdk.Key.Return) // ok
+	foreach (Gtk.Widget w in representation)
+		if (w.Name == "new") {
+			string text = ((Gtk.Entry)w).Text;
+			if (text != "")
+				representation.Add(new Gtk.Button(text));
+			w.Destroy(); // bye bye
+		}
+
+Steps to reproduce the problem:
+1. Compile the above lines of code
+
+Actual Results:
+
+Compile error:
+
+A local variable named `w' cannot be declared in this scope because it
+would give a different meaning to `w', which is already used in a `parent'
+scope to denote something else(CS0136)
+
+Expected Results:
+
+Compiles fine since the second foreach w is in a different if block than
+the first foreach w.
+
+How often does this happen? 
+
+Always
+
+Additional Information:
+
+Using Mono 1.2.3.1.
