为什么在C ++ 11中没有`static_if' [英] Why there is no `static_if` in C++11

问题描述

我不知道为什么像 static_if 这样的自然东西不能进入C ++ 11？有些人反对使用继承或模板专门化我们可以实现要求的结果：

I wonder why such a natural thing like static_if did not manage to get into C++11? Some people object that using inheritance or template specialization we could achieve demanded results BUT:

为什么我们没有一个简单的 static_if

Why don't we have a simple static_if for simple situations when one doesn't want to bloat up the source code with all that?

推荐答案

对于简单的情况，当我不想使所有的源代码膨胀时commitee没有时间讨论这个功能，所以他们决定延迟它在C ++ 11后。无论如何，建议都在这里： http://www.open-std.org /jtc1/sc22/wg21/docs/papers/2012/n3329.pdf

I suppose the commitee was short of time to discuss this feature so they decide to delay it after C++11. Anyway proposal is here: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3329.pdf
