([](auto &&...) {}(__VA_ARGS__))

"Thread-safe", multi-argument replacement for SCOPED_TRACE.

On some platforms, including Solaris, GTest does not define GTEST_IS_THREADSAFE. Then, use of SCOPED_TRACE in multiple threads results in random crashes because it compiles and runs without warnings but does not synchronize between threads.

To avoid random crashes, use MY_SCOPED_TRACE instead. The downside is that on those platforms, the "scoped traces" are empty, i.e., you see less debug info when a test assertion fails.

SCOPED_TRACE only takes one argument. Sometimes it is convenient to pass multiple arguments. This macro accepts multiple arguments and concatenates them using mysql::strconv::throwing::concat.
