Proposing a C++1Y Swap Operator, v2

by Walter Brown

Excerpt:

We propose a new swap operator on native types for incorporation into the C++1Y core language. For user-defined types, we propose that this new operator be treated as a special member function, and that, when viable, its presence provide an alternative to traditional memberwise implementation of defaulted assignment semantics.
