Discussion:

These sections define helper functions, some of which apply to `initializer_list<T>`. And they're available if you include one of a long list of header files, many of which include `<initializer_list>`. But they are not available if you include `<initializer_list>`. This seems very odd.

>     #include <initializer_list>
>     auto x = {1, 2, 3};
>     const int *p = data(x); // error, undeclared
>     #include <vector>
>     const int *q = data(x); // ok
