- Writable Iterator Concept
- .........................
- A class or built-in type ``X`` models the *Writable Iterator* concept
- if, in addition to ``X`` being Copy Constructible, the following
- expressions are valid and respect the stated semantics. Writable
- Iterators have an associated *set of value types*.
