Only the left hand doesn’t abnegate,the right hand doesn’t l

Christine Noblejas 说：When Economies negate Form drifts between Tampa (Florida) and Sonapur (Dubai).The Western site is essentially a place for dying,whereas its Eastern counterpart paves the way for a future yet to come:a modern utopia in the desert.The exhibit also explores Elderly camps in Dubai,which are no longer integrated into the city fabric.These camps run entire sub-economies,with bespoke currencies,where people either trade DVDs for Mangos or buy rooms that will return to the portfolio of the corporation the moment they die.

函数对象的一个小问题
比如说有个类如下：
class Negate
{
public:
int operator() (int n) { return -n;}
};
我看书在使用时,是直接Negate( ),对此我有点不解,Negate( )到底表示什么,表示是新建的Negate类的一个对象吗?如果是的话,为什么可以直接用Negate( )产生新对象?
还是有点不解,比如：
#include
using std::cout;
void Callback(int n,Negate & neg)
{
int val = neg(n); //调用重载的操作符“()”
cout
