推荐答案

2.6替代令牌[lex.digraph]

2.6 Alternative tokens [lex.digraph]

$ b一些运算符和标点符号16

1 Alternative token representations are provided for some operators and punctuators.16

2 在语言的所有方面，每个替代令牌分别表示

2 In all respects of the language, each alternative token behaves the same, respectively, as its primary token, except for its spelling.17 The set of alternative tokens is defined in Table 2.

相同。
如果你想尝试和说服自己一个是比另一个更好，这是你的业务。

So they are absolutely identical. If you want to try and convince yourself one is "better" than the other, that's your business. If someone else is trying to argue such, they'd better have a good reason.

编辑：上面的表2：

Table 2 — Alternative tokens
Alternative Primary
<%          {
%>          }
<:          [
:>          ]
%:          #
%:%:        ##
and         &&
bitor       |
or          ||
xor         ˆ
compl       ~
bitand      &
and_eq      &=
or_eq       |=
xor_eq      ˆ=
not         !
not_eq      !=

编辑：可能值得注意，根据 Sebastian Redl ，MS在这里违反规则。

Maybe worth noting, according to Sebastian Redl, MS break the rules here.
