"[...]a work-around that should make people's stomach crawl: write a wrapper that performs move-on-copy, much like the deprecated auto_ptr"
Unlike auto_ptr, this doesn't require a heap allocation.
| Name | Description |

MoveWrapper [constructor] | Constructors |
operator= | Assignment operators |
move | move the value out (sugar for std::move(*moveWrapper)) |
operator* | Access the wrapped value. |
operator-> | Access members of the wrapped value. |
| Name | Description |
|---|---|
makeMoveWrapper | Make a MoveWrapper from the argument. Because the name "makeMoveWrapper" is already quite transparent in its intent, this will work for lvalues as if you had wrapped them in std::move. |
