<pre>C++20 says nothing about the behavior of [[nodiscard]] on a constructor; it
would be useful for that to result in a warning for RAII temporaries:
PrettyStackTraceString("oops"); // warning
PrettyStackTraceString stackTraceRAII("okay"); // no warning
(I suppose this behavior would also apply to [[nodiscard]] on the entire class,
which it currently doesn't.)</pre>
