如果可以重载，那代码里所有的语句块所使用的{}，怎么办？

//C++ Operators
//  Operators specify an evaluation to be performed on one of the following:
//    One operand (unary operator)
//    Two operands (binary operator)
//    Three operands (ternary operator)
//  The C++ language includes all C operators and adds several new operators.
//  Table 1.1 lists the operators available in Microsoft C++.
//  Operators follow a strict precedence which defines the evaluation order of
//expressions containing these operators.  Operators associate with either the
//expression on their left or the expression on their right;    this is called
//“associativity.” Operators in the same group have equal precedence and are
//evaluated left to right in an expression unless explicitly forced by a pair of
//parentheses, ( ).
//  Table 1.1 shows the precedence and associativity of C++ operators
//  (from highest to lowest precedence).
//
//Table 1.1   C++ Operator Precedence and Associativity
// The highest precedence level is at the top of the table.
