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*.
