<pre>In the C++11 standard, [array.overview] paragraph 2 basically gives the
following as a normative statement of how to initialize a std::array.
#include <array>
void f(const int& x) {
std::array<int, 3> y = {x, x, x};
}
However, Clang warns on this, with "suggest braces around initialization of
subobject". See, e.g., <a href="https://godbolt.org/g/lZ3tn3">https://godbolt.org/g/lZ3tn3</a>.
It seems a bit weird to get a warning on things that the standard considers
normative!</pre>
