| [section:Protocol Protocol requirements] |
| |
| A type `X` meets the `Protocol` requirements if it satisfies the requirements |
| of `Destructible` (C++Std [destructible]), `CopyConstructible` (C++Std |
| [copyconstructible]), and `CopyAssignable` (C++Std [copyassignable]), as well |
| as the additional requirements listed below. |
| |
| No copy or move operation of the type `X` shall exit via an exception. |
