Topic: Why not have fixed vectors?

Really, why not have something like

template<typename T, size_t size> class fixed_vector
{
...
 typedef T data_array[size];
 unsigned char buffer[sizeof(data_array)];
 // Memory to place vector elements
 // Implementation dependent.
...

}

where ... stands for an adoptation of vector<T> for this
no-memory-allocation case.

Good compilers would inline everything in fixed_vector and built-in arrays
would really become coplitly unnecessary.

The main point to have such class in the standrd is the portability issues:
It is impossible(?) to write such class in the implementaion-independent
way.

So what do you think ?
