Addresses GB 5
The wording describes example code including the call of a move constructor, but there is no requirement stated that T be move constructible.We would like to add a new Para 1 before existing paragraph:
Requires: Type T shall be MoveConstructible (Table 20) and MoveAssignable (Table 22).
However the MoveAssignable concept currently does not cover cases where the source and destination types may differ.
The requirements are implicit according to 18.104.22.168 [structure.specifications]p4. There is no desire to redundantly repeat a set of requirements.
