// Adaptor function objects: pointers to member functions.
// There are a total of 16 = 2^4 function objects in this family.
// (1) Member functions taking no arguments vs member functions taking
// one argument.
// (2) Call through pointer vs call through reference.
// (3) Member function with void return type vs member function with
// non-void return type.
// (4) Const vs non-const member function.
// Note that choice (3) is nothing more than a workaround: according
// to the draft, compilers should handle void and non-void the same way.
// This feature is not yet widely implemented, though. You can only use
// member functions returning void if your compiler supports partial
// specialization.
// All of this complexity is in the function objects themselves. You can
// ignore it by using the helper function mem_fun and mem_fun_ref,
// which create whichever type of adaptor is appropriate.

//This implementation will only be used if needed, that is to say when there is the return void bug
//and when there is no partial template specialization
