        <pre>In the following snippet, the && on the function parameters are not aligned
consistently. From the snippet below it seems to be due to the decltype and the
missing name of the last function argument:


// minimal example: inconsistent T&& vs U &&
template <typename T, typename U> auto bar(T&& t, U &&) -> decltype(int());
// In the following it does not happen:
template <typename T, typename U> auto bar0(T&& t, U&&) {}
template <typename T, typename U> auto bar1(T&& t, U&&);
template <typename T, typename U> auto bar2(T&& t, U&& u) -> decltype(int());
template <typename T, typename U> auto bar3(T&&, U&& u) -> decltype(int());

// So it seams related to missing name of the last function argument and
// decltype

// it happens consistently inside structs:
struct baz {
  template <typename T, typename U> auto bar(T&& t, U &&) -> decltype(int());
  template <typename T, typename U> auto bar0(T&& t, U&&) {}
};</pre>
