If no constructors are specified in a mixin instantiation, the default zero-argument (zeroary) constructor is assumed.

如果在mixin实例化中没有指定任何构造器，那么就假定是缺省的不带参数的(zeroary)构造器。

I'm first printing the zero argument which I said is the name of the program itself.

我先打印参数,这是那个程序本身的名字。

Many economic arguments are about tradeoffs, but the argument for the zero tax rate of savings, also similar to the arguments for a consumption tax, is usually phrased as an argument about fairness.

FORBES: Taxing Capital Isn't About Fair: It's About Efficiency

Again, it is the efficiency argument which is the basis for the differential, even zero, taxation of capital gains and other income from capital.

FORBES: Taxing Capital Isn't About Fair: It's About Efficiency

But if the efficiency argument is weak evidence, the fairness argument is assumed to make the case, and make it for zero percent taxation.
