- [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.
