+Summary: Anonymous delegates let shadow variables
+Description of Problem:
+Gmcs ( lets shadow a parent scope variable in a child scope, if
+the inner scope is an anonymous delegate. This leads to ambigous variable
+resolution. Microsoft compiler rejects such code.
+Steps to reproduce the problem:
+1. gmcs the following code:
+delegate void D();
+class A{
+    static void Main(){
+        int i;
+        D d = delegate {int i;};
+    }
+Actual Results:
+Expected Results:
+Report an error, like the Microsoft compiler does.
+"A local variable named 'i' cannot be declared in this scope because it
+would give a different meaning to 'i', which is already used in a 'parent
+or current' scope to denote something else"
+How often does this happen?
