  /**
   *  @brief  An allocator that uses global `new`, as per C++03 [20.4.1].
   *  @ingroup allocators
   *
   *  This is precisely the allocator defined in the C++ Standard.
   *    - all allocation calls `operator new`
   *    - all deallocation calls `operator delete`
   *
   *  This is a non-standard extension that can be used to guarantee
   *  allocation from `new` even if the library has been configured to
   *  use a different implementation for `std::allocator`.
   *
   *  @tparam  _Tp  Type of allocated object.
   *
   *  @headerfile ext/new_allocator.h
