1. Remove 17.11.5 [support.initlist.range]:

// all freestanding

namespace std {

  template<class E> class initializer_list {

  public:

    using value_type      = E;

    using reference       = const E&;

    using const_reference = const E&;

    using size_type       = size_t;

    using iterator        = const E*;

    using const_iterator  = const E*;

    constexpr initializer_list() noexcept;

    constexpr size_t size() const noexcept;     // number of elements

    constexpr const E* begin() const noexcept;  // first element

    constexpr const E* end() const noexcept;    // one past the last element

  };

  // [support.initlist.range], initializer list range access

  template<class E> constexpr const E* begin(initializer_list<E> il) noexcept;

  template<class E> constexpr const E* end(initializer_list<E> il) noexcept;

}

I tried submitting it as a standard library issue, but the LWG chair said it needed a proposal. Can someone help?
