I am having an issue with wrapping my head around an apparent ambiguity in the c++0x spec, see also: http://www.nongnu.org/hcb/
Is it possible to construct function call (inside function template) with variable number of arguments, depending on number of template arguments? Something like:

What is the precedence of the meta-operator ... whose job is to unpack template type parameter packs? I imagine it\'s pretty low, but how low is it? The C++ standard says:
Firstly, I\'m aware of this question, but I don\'t believe I\'m asking the same thing. I know what std::vector<T>::emplace_back does - and I understand why I would use it over push_back().It us

Does the standard define precisely what I can do with an ob开发者_运维知识库ject once it has been moved from? I used to think that all you can do with a moved-from object is do destruct it, but that w
