<pre>$ cat 1.cc
#include <memory>
typedef float T __attribute__((__vector_size__(16)));
void f(T t) {
std::unique_ptr<T[]> ptr(new T[5]);
ptr[0] = t;
}
$ clang++ 1.cc -c -std=c++11 -stdlib=libc++
1.cc:13:10: error: expression is not assignable
ptr[0] = get();
~~~~~~ ^
1 error generated.
It looks like __is_referenceable<T> is false and unique_ptr<T>::operator[]()
gets T as the return type instead of T&.</pre>
