VS2010 C++编译问题

[csharpplus1]

template<bool val> class static_assert ;
template<> class static_assert<true> {};

好像就是上边2句的问题，请问这是什么错误啊

猜测：
template <bool val> class static_assert {};

是否先得 定义？然后才能特化？

[jackyjkchen]

template <>这种东西也少出现

[珍惜生命远离CPP]

static_assert已经升级到关键字了 ...

强悍啊,不太懂就能写这样的代码,佩服.

其实是想说，用 VC 2010 就有必要了解一下 C++0x……
