C++14: Runtime-sized arrays

More details on the ISO C++ blog about runtime-sized arrays in C++14.

N3639 proposes to add local runtime-sized arrays with automatic storage duration to C++, for example:

void f(std::size_t n)
int a[n];
for (std::size_t i = 0; i < n; ++i)
a[i] = 2*i;
std::sort(a, a+n);

Traditionally, the array bound “n” had to be a constant expression.
