This repository contains two C++ Standards proposals and their sample implementations. The two proposals both have to do with allocators, but are otherwise pretty loosely coupled. They exist in the same directory just because it was convenient at the time. That may change in the future.
This paper proposes a set of utility functions to make it more convenient to
implement allocator-aware containers. These functions can also make the
standard more readable by centralizing the logic for constructing objects
using allocators, including std::pair, which does not use an allocator
directly, but which may contain members that use allocators.

This paper proposes utility functions that more cleanly express the copy-swap idiom used for exception safety and make the idioms work correctly with different allocator propagation traits.
