Discussion:
scoped_allocator_adaptor is specified to use forward when what it is really doing is moving elements. It should use move.
Previous resolution [SUPERSEDED]:
This wording is relative to N4582.
Edit 20.6.4 [allocator.adaptor.members] p15 as indicated:
template <class T1, class T2, class U, class V> void construct(pair<T1, T2>* p, pair<U, V>&& x);Effects: Equivalent to
this->construct(p, piecewise_construct, forward_as_tuple(std:: forward move<U>(x.first)), forward_as_tuple(std:: forward move<V>(x.second))).
Proposed resolution:
Withdrawn by the submitter, since the prerequisites were incorrect.
