//
// This tests only checks if we can compile the program.
//
// The trick is that we are accessing a protected property, with the way
// mcs deals with properties in two steps (property first, method next)
// this text excercises some eager optimizations in the TypeManager.FilterWithClosure.
//
//
// The second class excercises accessing private members from a container class
//
// The third class excercises accessing a private/protected value on an instance of
// a child
