p0960在r1和r2之间更改：

p0960 changed between r1 and r2:

r2：此修订将心理模型从原始的将文字重写为括号列表更改为 ，就像调用了带有适当的mem-initializers的综合显式构造函数一样。 ¹ 。即使在相应的括号列表语法中禁止缩小转换的情况下，也具有允许在括号列表中缩小转换的效果。它还阐明了不延长引用临时对象的临时寿命，不存在大括号省略和不存在对参数进行明确定义的求值顺序。

r2: This revision changes the mental model from the original "literal rewrite to a braced list" to "as if a synthesized, explicit constructor with appropriate mem-initializers was called"¹. This has the effect of allowing narrowing conversions in the parenthesized list, even when narrowing conversions would be forbidden in the corresponding braced list syntax. It also clarifies the non-extension of temporary lifetimes of temporaries bound to references, the absence of brace elision, and the absence of a well-defined order of evaluation of the arguments.

进行此更改的原因可以在已更改的p0960设计原理中找到：

The reason why this change was made can be found in the changed design principles for p0960:

r1：括号内的初始化和括号内的初始化

r1: Parenthesized initialization and braced-initialization should be as similar as possible.

r2：
括号化的初始化和支撑初始化应尽可能相似，但必须与众不同，以与现有的一致括号列表和括号列表的心理模型。
（强调我的）

为什么p0960没有采用更简单的方法（）初始化，更像{}？：

当决定与现有心理模型保持一致时 ¹ 已被采用，不允许括号删除似乎是 only 方法。

When the decision to go for conformance with the existing mental models ¹ had been taken, not allowing brace elision seems like the only approach.
