Sorry, it is not what I expected. some_array_ref = std::array<...>{...} is always wrong...

std::array<...>{...} is a temp value. It is different from below, which is correct:

std::array<...> a{...};
some_array_ref = a;

Please note that a is a named variable, which is killed at the end of the scope, while some_array_ref = std::array<...>{...} kills the array after the end of the statement.

While dealing with arrayref, please always pay attention whether the thing you pass into the ref has a longer lifetime than the ref itself.

Also I suggest using std::array<...>{x,y,z} over std::array<...>({x,y,z}). The () are redundant, and will trigger ambiguous-error in some old compilers.
