behavior compiler

基本解释

If you want the compiler's previous behavior, remove the array from the constructor's member initialization list.
如果您要编译器的旧行为，请将该阵列从建构函式的成员初始设定清单中移除。
Leaving it to the compiler to implement the default behavior is simpler, less error-prone, and often leads to better object code.
留给编译器来实现缺省行为更简单些，更不易出错，并且常常会产生更好的目标码。
The reason for this behavior is that, at compile time, the compiler only knows that T is a reference type, and therefore must use the default operators that are valid for all reference types.
这种情况的原因在于，编译器在编译时仅知道 T 是引用类型，因此必须使用对所有引用类型都有效的默认运算符。
