// Koenig lookup + explicit instantiation = access specifiers ko.
// a modified version of a well known hack (C++standard/sutter/litb/dabrahams/...)
// purpose is to deal with static private member functions and violate access specifiers
// exercise is not about the access specifiers, but about where get() is actually found
// compiles C++0x
