Addresses: fund.ts.v3
The LFTSv3 prospective-working-paper N4758 contains two aliases that are already in C++17:
void_t in 99 [fund.ts.v3::meta.type.synop]
uses_allocator_v in 99 [fund.ts.v3::header.memory.synop]
I'd like to propose deleting both, but separate discussion is warranted:
void_t belongs with the larger "detection idiom", which has not been merged into C++17. We may prefer
to keep our own local version of the alias.
uses_allocator_v aliases a version of uses_allocator that is modified by this TS. However,
as specified the alias may actually end up referring to std::uses_allocator (because
<memory> is included), not to std::experimental::uses_allocator, as may have been intended.
