关于模板化命名空间的WG21论文 [英] WG21 paper on templated namespaces
问题描述
大家好，
我一直在搜索论文列表：
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/
我似乎记得有关模板命名空间的提议，例如：
模板< typename T>
命名空间X {
}
不幸的是我无法找到它。有谁知道我正在考虑或者我刚刚发明的那张纸的名称/号码？
问候

该怎么办？

它是什么SUP提出要做什么？
我有时会使用一个结构来分组东西以帮助源代码
易读性并节省输入：
模板< typename T>
结构长度{
typedef something_ugly< T，...> mm;
typedef somethingelse_ugly< T，...> m;
};
//声明something_ugly
长度< double> :: mm mylength;
结构的问题是你无法重新打开它，这将是一个理想的功能。也许我想添加英寸：
模板< typename T>
命名空间长度{
typedef something_else_again< T，.. > in;
}
长度< double> ::在mylength1;
我以为我见过ia有关此问题的论文，但现在无法找到。
有人知道我在说什么吗？ （嗯，我真的想要这些家伙吗？
回答那个？... ;-)

易读性和节省打字：

//声明一个something_ugly
长度< double> :: mm mylength;

模板< typename T>
名称空间长度{

}
长度< double> :: in mylength1;
现在，告诉我，为什么不能你在原始结构中添加英寸？
命名空间有一定的用途。主要是为了防止名称冲突
并且为了清晰起见而不保存打字或分组。
我以为我曾经看过关于此的论文，但是不能现在找到它。有没有人知道我在说什么？ （嗯，我真的希望这些家伙
回答这个问题吗？... ;-)）
尝试询问''comp.std.c ++' '，但是。

Hi all,
I have been searching through the list of papers at:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/
I seem to remember a proposal regarding templated namespaces e.g:
template <typename T>
namespace X{
}
Unfortunately I cant find it. Does anyone know the name/number of the
paper I''m thinking of or have I just invented it?
regards

I sometimes use a struct for grouping stuff to help in source code
legibility and to save typing:
template <typename T>
struct length{
typedef something_ugly<T,...> mm;
typedef somethingelse_ugly<T,...> m;
};
// declare a something_ugly
length<double>::mm mylength;
The problem with a struct is you cant reopen it, which would be a
desirable feature. Maybe I want to add inches:
template<typename T>
namespace length{
typedef something_else_again<T,...> in;
}
length<double>::in mylength1;
I thought I had seen i a paper about this, but cant find it now. Does
anyone know what I''m talking about? (hmm do I really want these guys to
answer that? ... ;-) )

Now, tell me, why can''t you add inches to the original struct?
Namespaces have a certain purpose. Mostly it''s to prevent name collisions
and not save typing or grouping for legibility''s sake.

Try asking in ''comp.std.c++'', though.
