Discussion:
LWG 2193 yields explicit for default ctors to allow {}, but not for all cases of uniform initialization. For example:
explicit vector(size_type count, const Allocator& alloc = Allocator());
This prevents {n, alloc()}. Although this use is relatively rare, but the behavior is inconsistent with that of
vector(size_type count, const T& value, const Allocator& alloc = Allocator());
