c++ - 项目符号 [dcl.init]/7 (7.1)

Question

我明白了[dcl.init]/7 (7.1)由于 DR 1630，相对于 C++14 进行了更改.但是 C++14 中突出显示的句子(见下文)不应该继续存在于 C++1z 中吗？

[dcl.init]/7 (7.1):

If T is a (possibly cv-qualified) class type (Clause 12), constructors are considered. The applicable constructors are enumerated (16.3.1.3), and the best one for the initializer () is chosen through overload resolution (16.3). The constructor thus selected is called, with an empty argument list, to initialize the object.

C++14 中的[dcl.init]/7 (7.1)(重点是我的):

if T is a (possibly cv-qualified) class type (Clause 9), the default constructor (12.1) for T is called (and the initialization is ill-formed if T has no default constructor or overload resolution (13.3) results in an ambiguity or in a function that is deleted or inaccessible from the context of the initialization);

Answer 1

... and the best one for the initializer () is chosen through overload resolution ...

过载解析已经暗示了所有被删除的内容。使用旧的措辞，在没有提到限制的情况下，它可以被理解为隐含地允许调用不可访问的默认构造函数，但使用新的措辞，通过简单地指定适用通常的规则就已经很清楚了。
