Hello. I'm trying to implement a variadic vector type in c++0x with
the variadic templates proposal (in gcc-4.4).
I tried with this, and I wonder why I can't do this.
template <class...Values>
class vector {
private:
//This is not legal
Values v...;
....
};
I think this should be allowed and a way to access every v would be to
give v, v2, v3 names to the unpacked parameter pack or something
similar.
Now I'm trying to do this, which is legal:
template <class... Values> class vector;
template <class Head, class...Tail> class vector<Head, Tail...> :
vector<Head, Tail...>
{
private:
Head head_;
};
But the problem is that as every head_ variable shadows its base head_
variable, I don't know how to access them. It woul also be nice to be
able to implement operator[] as a constexpr to be able to index
the vector like v[0] and so on, but I think it's not possible.
Anyway, I think the syntax to expand variables (first example) should
be legal because doing what I'm doing in the second example is
unnecessarily complicated.
