   4 // The trick is that we are accessing a protected property, with the way
   5 // mcs deals with properties in two steps (property first, method next)
   6 // this text excercises some eager optimizations in the TypeManager.FilterWithClosure.

   8 //
   9 // The second class excercises accessing private members from a container class
  10 //
  11 // The third class excercises accessing a private/protected value on an instance of
  12 // a child
