// The following traits classes allow us to avoid the need for ptr_fun
// because the types of arguments and the result of a function can be
// deduced.
//
// In addition to the standard types defined in unary_function and
// binary_function, we add
//
// - function_type, the type of the function or function object itself.
//
// - param_type, the type that should be used for passing the function or
// function object as an argument.
